Development of Sliding Mode Control Strategies and
Haptic Feedback for Permanent Magnet
Synchronous Motor (PMSM) Actuated Sidestick
Content
The avionics society is in constant demand to optimize aircraft performance and improve the in-teraction between pilots and aircraft. This paper aims with the design and implementation of a stable nonlinear sliding mode control strategy and haptic feedback on PMSM actuated sidesticks to improve the tracking performance. The controller currently used in aircraft is a cascade of PID controllers in a linearized system, which cannot be considered more than a local solution as it doesn’t necessarily prove the stability in realistic conditions. Several nonlinear strategies were attempted on the model which accurately represents the new generation sidestick system pow-ered by the permanent magnet synchronous motor (PMSM) actuator. Eventually, sliding mode nonlinear control strategy is considered as it provides solid stability while ensuring the desired performance. Furthermore, the execution of haptic feedback aims at fulfilling the lack of commu-nication from the aircraft to the pilots, especially at extreme flight conditions. The pilot’s arm is assumed as a mass-spring-damper system ( to consider muscles stiffness and damping with the human response time) where force feedback is provided to the pilot for the command input. In conclusion, all the above-mentioned strategies are tested on a real sidestick system based on an innovative direct-drive linear actuator.
