摘要
为提升控制力矩陀螺外框架系统的动态性能,本文建立了基于永磁同步电机的控制系统模型、设计了一种适用于其外框架系统的模糊PID控制器,并进行了Simulink仿真验证。仿真结果表明,具有参数自调整特性的模糊PID控制方式比起普通PID控制方式具有更短的调整时间及跟踪性能,满足动态性能提升的设计目的。
In gontrol moment gyroscope（CMG）, momentum wheel rotor that rotates at high speed could form angular momentum, and the outer frame motor that drives the momentum wheel to rotate could generate the control torque, then the control torque could adjust satellite attitude. In order to improve the dynamic performance of the outer frame system, a fuzzy PID controller is designed which could be suitable for the optimization of the outer frame system of the CMG, then the Simulink simulation is carried out. The simulation results show that the fuzzy PID control method with parameter self-tuning characteristics has shorter adjustment time and better tracking performance compared with the conventional PID, that satisfies the design purpose of the optimization performance.
