摘要
针对存在传输滞后的线性离散系统的状态反馈镇定问题,给出了系统可镇定的一个内部限制条件.为克服这一限制条件,提出了两种方法:一种是充分利用滞后状态的信息,另一种是设计带有递推动态的状态反馈控制器.研究结果表明,若系统在没有传输滞后时能通过状态反馈被镇定,则存在传输滞后时一定也能通过设计新的控制器使系统被镇定.
For the problem of state feedback stabilization for linear discrete systems with transmission delays, an inherent limitation for the stabilization problem is obtained. In order to overcome the inherent limitation,two methods are proposed. One is using enough information of the delayed states. The other is designing recursive state feedback controllers. Research results show that if a system without transmission delay can be stabilized by a state feedback, the one with transmission delay still can be stabilized by the designed state feedback controller.
