摘要: 基于一个新的Riccati型方程的对称正定解,对于不确定线性连续控制系统,提出了 一种新的鲁棒容错反馈设计方法,利用该方法设计的闭环系统,不仅针对执行器发生故障时 具有完整性,而且关于参数不确定性具有鲁棒稳定性.该方法简单易行,并用一个示例及仿真 结果验证了该方法的有效性.Abstract: Based on a symmetric positive definite solution of the new Riccati-type equation, a new design method of robust fault-tolerant feedback controller is put forward for uncertain continuous-time control systems. It is shown that the proposed state feedback system preserves asymptotic stability in the presence of parameter perturbations ,as well as in the case of actuator failures. Moreover, a design procedure is proposed, and the effectiveness of the procedure is demonstrated with a numerical example and simulation results.
