The More Electric Aircraft - Why Aerospace Needs Power Electronics... Software !


Here is a great presentation from Prof. Pat Wheeler of the University of Notthingham, United Kingdom. From this presentation, we can outline the following:

  • A movement from "old" pneumatic/hydraulic/mechanic actuator technology into inverter powered electrical motors technologies
  • For a same 40MW Propulsion Thrust output, losses are reduced by nearly 59% (1.7MW to 1MW)
  • Other benefits: reduced weight, easier maintenance, more contrallibility and intelligence (fault detection and diagnosis)
  • Power electronics improve both generator (mechanical to electric) and actuators (electric to mechanical) energy conversions and enable energy regeneration

This leads aircraft manufacturers to design safer and quieter planes that can flight longer distances with less fuel. This is why aerospace industry needs more power electronics... software!

Please find below how Alizem embedded motor control software for critical applications can contribute to "more electric aircraft" and help aircraft system designers to win in their market:

Alizem releases its new Embedded Motor Control Software IP for Critical Applications

For immediate release
Alizem releases its new Embedded Motor Control Software IP for Critical Applications

Lévis (CANADA), February 18th 2014. Alizem is proud to announce the release of its new Embedded Motor Control Software IP for Critical Applications based on a technology invented and developed at the Canadian Space Agency (CSA). This solution is meant to work with BLDC and PMSM motors operating in applications where energy-efficiency and reliability are critical. It offers significant benefits to inverter-fed electric motor drive system designers:

  • Optimal management of phase current distribution lowering losses and enhancing maximum achievable torque and speed by 20% leading to lower motor rating, weight, space and cooling requirements
  • Ripple-free torque leading to reduced mechanical stress, velocity fluctuation, noise and higher reliability and tracking accuracy in servo applications
  • Automatic fault recovery from a phase winding failure and/or phase voltage/current saturation
  • Capability to provide critical information regarding motor health to master system (M2M, machine-to-machine)
  • Easy-to-use application programming interface (API) for quick and safe operation including multiple debug modes for power stage, transducer and system protection verification for early bug detection

This software can be ported and run on any type of electronic device that fits motor control applications and integrated into new or existing electric motor drive systems.

“Critical applications are numerous ranging from airplane brake systems, robotics and electric vehicles to HVAC systems installed in a nuclear plant. In many of those applications, electric motors play a central role and failure may lead to catastrophic human and financial consequences” said Dr. Marc Perron, President at Alizem. “This is why the motor control software installed in those motor drive systems must not only deliver excellent operational performance but must also be robust to motor damage in order to reduce the risk of failure and downtime. This also includes consuming as low energy as possible to maximize operation time when systems are operating from a limited energy source such as batteries or gas tank. This new product is a great way to address this problem without investing all the efforts needed to develop this technology. This is how Alizem helps its customer to get more innovation in their product better, faster and cheaper.”

5 reasons to choose Alizem Software IP in your next motor drive system development project

Mentor's Colin Walls has released a very good article yesterday titled "Using software IP: best practices for embedded systems design" on the general benefits of using software IP in general embedded system design.

Those benefits are also true for motor control software IP but an important step in using software IP is to choose the good one from a competent vendor. Here is how Alizem IP positions on 5 important criteria for software IP selection listed by the author:

1- Functionality

This is a very important question especially in power electronics applications where there exists hundreds if not thousands of different way to achieve the same functionnality (not including the unique software variations that are caused by limitations of each electronic devices). This is the reasons why Alizem bundle its product as "application-specific products". Motor control of a 500W washing machine motor is not the same as a 500W power steering system. Hence, Alizem IP are tailored to fit specific motor control applications and bundled with all functions needed to achieve top performance and fast integration.

Alizem is software IP is currently in use in applications from 30W to 86kW.

2- Quality

As a software company, Alizem knows about the importance of having a controlled software development process to make sure its software is developped and tested with the highest standard possible (our process is CMM-like). Since Alizem software is used to control energy, the impact of a bug can be disastrous: system damage, electrocution, etc. Hence, every software version that is realeased is tested on a real testbench with a real motor.

Also, Alizem has recently received the AMPP certification, the highest IP quality certification delivered by Altera.

3- Price

Alizem Software IP prices are set to be absolutely compelling against the cost of developping its own software from scratch.

4- Licensing 

Software IP licensing allows our customer to pay for the IP when they enter in production, i.e. when revenues comes in. In a world of economic uncertainty, this is a very compelling option that reduces financial risk of any product development project.

5- Core compentency

Alizem is entirely dedicated to the world of power electronics applications. Our team has nearly ~100 years of experience in this field.

How Alizem addresses the Top 6 Challenges in Electronics Manufacturing

Recently, an excellent article has been published by Mike Roberts on the Product Design and Development website, addressing the top 6 challenges in Electronics Manfacturing. Here is how Alizem COTS embedded software contributes in solving those challenges :

1. Shrinking Operating Margins: Global competition and new innovations are driving prices down. Companies must continually become more cost-efficient to remain profitable. 

Alizem offers off-the-shelf expertise in embedded software and power electronics applications. You get the best of the the worlds: rare-to-find world-class expertise, on tap. This approach helps you bring constant innovation in your products at reduced costs, risks and time-to-market.

2. Complex Global Supply-Chain: More and more, companies have to juggle internal and external resources while staying within international standards. Issues such as traceability and compliance are increasing operational burdens. It is not unusual for components and sub-components to embark on a journey that touches three or more continents before reaching the end-consumer.

3. Service and Warranty Management: Leveraging the global supply-chain is putting more focus on supplier quality management. Having a strong quality and traceability system directly affects warranty reserve and post-production service hours. 

Alizem software products are delivered over internet directly to customer worldwide. No inventory is needed. No domain experts are required.

4. Short Product Lifecycles: With quickly changing consumer tastes and preferences, EMS companies and contract manufacturers need to have effective New Product Introduction (NPI) processes in place. Closed-loop communication between sales, manufacturing, and engineering is vital to ensure product launches hit time, volume, and quality targets.

Alizem offers application-specific, pre-tested and directly integrable embedded software. Knowing that embedded software development accounts for a high proportion of a project costs and risks, this is a great way to shorten product lifecycles while keeping focus on product differentiation.

5. Uncertain Demand: Aggregately, economic volatility and cyclical demand cause fluctuations in production. On a more granular level, consumer preference can cause spikes in demand for an individual product or company. Efficient lean capabilities must be in place to keep inventory aligned with demand.

Alizem on-tap expertise and products are delivered when needed allowing our customers to freely adjust their schedule and easily go through any economic downturn or exceptional events. Also, Alizem offers its products through flexible licensing agreements that enable development system costs to be delayed up to production (revenues).

6. Sustainability: Emerging regulations and standards are forcing companies to account more and more for Corporate Social Responsibility (CSR) in decisions. E-Waste, a popular topic today, is driving conversations about the disposal of products and their impact on the environment. Companies must now consider of the complete product lifecycle in decisions.

Alizem products are "virtual goods" that, according this study, account for -30% GHG savings. They are in line with the large trend of virtualization and dematerialization.
