【摘要】 针对一类具有范数有界参数不确定性的非线性系统和一个二次型性能指标,提出了在执行器故障时保性能控制器的设计方法。采用线性矩阵不等式的方法,得出了系统在执行器故障时保性能控制律存在的充分条件,使系统对允许的不确定性具有鲁棒性,并达到一定的性能指标。仿真结果表明该方法的有效性。更多还原

【Abstract】 For a class of nonlinear systems with norm-bounded-parameter uncertainty and a quadratic cost index, the problem of designing guaranteed cost state feedback controllers with actuators fault is suggested. Based on LMI (linear matrix inequation), the guaranteed cost fault tolerant controller with uncertainties is derived. The simulation results demonstrate the validity of this method.更多还原
