摘要: 考虑带有Frobenius范数界的不确定广义系统,具有完整性的鲁棒二次稳定问题.用 Riccati不等式给出不确定广义系统在状态反馈和输出反馈作用下所构成的闭环系统二次稳定, 并且当执行器出现故障时,不确定广义系统仍能保持二次稳定的充分条件,即不确定广义系统 具有完整性的鲁棒二次稳定的充分条件.Abstract: In this paper, robust quadratic stabilization owning integrity is explored for an uncertain descriptor system with Frobenius-norm bound. By algebraic Riccati inequality, sufficient conditions for quadratic stabilization of the uncertain descriptor system are given by means of state feedback and output feedback. Meanwhile, the feedback control is designed so as to keep the resultant closed-loop system to be quadratically stable when the system actuator is fault, i.e., the system possesses integrity.
