Permanent Magnet Synchronous Motor Control of Electromechanical Actuator Based on Parameter Self-tuning Method

Abstract

With the wide application of electromechanical actuator(EMA) system in aviation industry, permanent magnet synchronous motor, as a key component of EMA, has a good application prospect due to its unique advantages. In this paper, based on the analysis of relevant research at home and abroad, the control system of PMSM with EMA is designed, and the control system model is built with MATLAB and the simulation experiment is carried out. At the same time, parameter self-tuning and fuzzy control methods are used to optimize the performance of the control system. In order to test the performance of the EMA servo control system, this paper designs the EMA system performance test platform, completes the hardware and software design of the test bench, and carries out relevant tests to test the performance of the optimized EMA system. The experimental results show that the parameter self-tuning method used in this paper has a very significant performance improvement for PID control.
