| 摘 要： | 提出一类广义线性离散系统的预见控制问题.首先,利用差分算子构造扩大误差系统,然后通过引入一些恒等式,把可预见的目标信号的差分也包含在扩大误差系统的状态向量中,把所考虑的广义系统的预见控制问题转化为一个形式上的普通广义系统的控制问题.由熟知的广义系统最优控制理论的结论,得到广义系统的带有预见作用的控制器.对扩大误差系统的R-能稳性和能检测性进行了详细讨论.

| Abstract: | A preview controller design method for a class of singular discrete-time linear systems is presented.By using the difference operator,a so-called extending error systemcan is obtained.Then by using the discrete-lifting technique,an augmented system is constructed.The state vector of the augmented system includes the desired output signal,and the problem is changed into an usual optimal control problem of singular discrete-time linear systems.The standard discretetime linear optimal control method is applied... |
