Simulation Analysis of an Electric Drive Device Based on Matlab

Abstract

With the development of multi-electric aircraft, the application of electric drive in aircraft is increasing day by day, but there are many peripheral circuits, high work number, poor reliability, slow corresponding speed and poor anti-interference ability in the single closed–loop DSP control circuit. In this paper, the electric drive device of a hatch door is taken as the research object, and the FPGA and double closed-loop control system is adopted to reduce power consumption and improve reliability. The inner loop adopts current hysteresis control and the outer loop adopts speed PI control, which make the system feedback more direct, fast and improve the adaptability and anti-interference ability of the system to working conditions. Through modeling and simulation, analyze dynamic and static performance index of the system, rapidity and stability of the controller system are analyzed and related components parameters, the performance of the control system of implementation index optimization allocation and the index in the experiment verification. Thus reduce the risk of design and development, reduce the development cost, and shorten the development cycle.
