摘要: 在最优预见伺服系统设计中通常只考虑阶跃型目标值函数。本文研究当自标值信号及干扰信号为多项式或为线性齐次系统的输出时最优预见伺服系统的设计问题,得到了如下三方面的结果:(一)扩大系统的能控性及能观测性条件;(二)最优预见控制器的设计方法;(三)控制规则的简便算法。Abstract: Usually, only siep future desired singals are utilized in the field of preview servo systems design. In this paper, we discuss the design problem of optimal preview servo system while the future desired signal and future disturbance signal are polynomials or outputs of linear free systems. (1) Conditions of controllability and observability for enlarged system, (2) A design method of optimal preview servo controllers,(3) A simple and convenient algorithm of control law are obtained.
