| 摘 要： | 针对具有不确定性的线性定常系统,提出了考虑执行器故障的圆盘极点可靠配置问题·在更一般、更实际的执行器故障模型的基础上,给出了将极点配置到指定圆盘内可靠控制存在的充分条件·通过求解LMI完成状态反馈可靠控制器的设计·利用仿真实例验证了本文提出设计方法的可行性,并且通过与不考虑故障和不确定因素的系统比较,进一步说明对系统进行可靠极点配置的必要性·

| Abstract: | ?The reliable placement of disk pole with actuator failures is discussed for the constant linear system with uncertainty. Based on a more common and actual model of actuator failures,the sufficient conditions are given to the reliable control when allocating the pole into an assigned circular disk. Then, a reliable state-feedback controller can be designed through solving LMI. A simulation test was carried out to verify the practicability of such a design procedure. Compared with the system taking no account of failures and uncertain factors, the necessity of allocating reliably the pole to a system is proved further. |
