摘要
本文通过分析Watanabe等人提出的改进型Smith预估控制(MSPC)方案,发现动态补偿器M(S)必须满足lim M(s)=1,否则当模型不匹配时,MSPC有稳态余差。同时作者还提出了一种简单的M(s)设计方法,并进行了实例演算,其结果和文献完全一致。
This paper analyses the modified Smith predictor control system proposed by Watanabe and finds that the dynamical compensator M(s) must be satisfied with the limitation of M(s) equaling one when s is near zero. Otherwise the MSPC will exist in a stady-state error. Meanwhile a simple procedure of M(s) is presented and some examples are given. The calculated results are identical to those in the refference
