Embedded Software forPower Electronics Applications

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

PRESS RELEASE
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.”

Customers interested in this solution have access to more technical information by consulting Alizem website or by contacting Alizem sales department.
