摘要
介绍了直流无刷电机的结构、控制方法,提出了带有DSP控制器的LQG控制系统。由于采用了数字信号处理(DSP),提高了电机控制性能,降低了成本,实现了理想控制。仿真实验表明,该控制系统能够弥补传统PID控制的不足,对负载扰动有良好的抑制作用。实验结果表明了它的可靠性和准确性,并体现了最优的设计思想。
This paper describes the structore of BLDCM,the way to control it and a new LQG control system with DSP.AsDSP is utilized in the motor controller,so the controller combines the high calculation power,lewer cost and higher performance.After the emulational practice,we have drawn the conclusion that the system an compensate the weakness d PID control, and it an also prevent the load disturbance.So the result shows its reliability, veracity and embodies the premium control.
