| 摘 要： | 针对目标信号和干扰信号为多项式的情形,研究了多采样率离散时间控制系统的最优预见控制问题.首先利用离散时间系统提升技术,把所研究的系统转化成单采样率的扩大系统.然后构造扩大误差系统,把问题转化为包含预见信号的最优调节问题.最后利用最优预见控制理论的结果得到系统的最优预见控制输入,其中包含积分器和预见前馈补偿.本文还对扩大误差系统的能控性和能观测性和相应的代数Riccati方程的可解性进行了讨论.

| Abstract: | The optimal preview control problem for multirate discrete-time systems subject to polynomial previewable desired output and polynomial previewable disturbance signal are discussed.By using method of lifting technique,the multirate preview control problem can be reduced to the single-rate one for a certain augmented system.Then using the method of error systems,we changed the problem into a standard linear regulator problem.By the standard LQ optimal preview control theory,we obtained the desired preview co... |
