中文摘要:
这篇论文学习与致动器浸透为线性时间不变的系统设计适应差错容忍的控制器的问题。为经由州的反馈设计间接适应差错容忍的控制器的新方法为致动器差错赔偿被介绍。基于最终的差错的联机评价,适应差错容忍的控制器参数自动地正在更新在系统上补偿差错效果。图案在线性矩阵不平等(LMI ) 的框架被开发来临,它能在致动器的情况中扩大靠近环的系统的吸引力的域浸透和致动器失败。二个例子被给说明设计方法的有效性。
英文摘要:
This paper studies the problem of designing adaptive fault-tolerant controllers for linear tirne-invariant systems with actuator saturation. New methods for designing indirect adaptive fault-tolerant controllers via state feedback are presented for actuator fault compensations. Based on the on-line estimation of eventual faults, the adaptive fault-tolerant controller parameters are updating automatically to compensate the fault effects on systems. The designs are developed in the framework of linear matrix inequality (LMI) approach, which can enlarge the domain of attraction of closed-loop systems in the cases of actuator saturation and actuator failures. Two examples are given to illustrate the effectiveness of the design method.
