一类Smith预估器及其鲁棒整定
Optimal Smith Predictor and its Robust Tuning
-
摘要: 提出一种Smith预估器解析设计方法,由此得到的控制器可以同时保证好的干扰抑 制特性和鲁棒性.证明该控制器可以通过常规的PID控制器来实现,并能根据给定的性能要 求(超调或调节时间)设计.Abstract: An analytical approach is presented for the design of Smith predictor, which provides disturbance rejection and robustness simultaneously. It is shown that the Smith predictor is equivalent to a PID controller and can be implemented by conventional PID controller. Its closed loop performance is also discussed. An example is included to illustrate superiority of the approach.
