| 摘 要： | 针对不同的速度给定,采用了一种增益自整定PI速度控制器。传统的PI控制器在参数不准确的情况下控制效果不理想,尤其是在速度给定频繁变化的情况下,控制效果不能很好地满足要求。此处采用的控制器克服了传统控制器的这个缺点。通过对期望速度与实际速度之间差值的运算,使比例增益和积分增益成为差值的函数,可以在一定范围内变化,从而实现增益的自整定。通过仿真和实验可知,该方法的控制效果较好,能够满足一般要求,从而验证了该方法理论的正确性和实际的可行性。

| Abstract: | A gain-scheduled proportional and integral(PI) speed controller is used for different given speeds.The traditional PI controller can not satisfy the dynamic and steady state performance when the parameters of the controller are not accurate and especially the given speed changes frequendy.The controller can overcome the drawbacks.The PI gains can become the functions of error and vary within a range through computing the error between the desired speed and the actual speed.The method has good performance and the correctness and the feasibility of the method are verifed by the results of simulation and experiment. |
