【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。更多还原

【Abstract】 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更多还原
