摘　　要：不仅研究了一类扰动控制系统鲁棒稳定界的定义、优化等问题 ,而且通过研究控制系统鲁棒稳定界与Riccati矩阵方程解的关系 ,提出了在闭环极点约束条件下研究鲁棒稳定界的方法 ,并给出了基于LQ逆问题参数化解的极大化鲁棒稳定界的优化算法 .The definitions and optimization problem of robust stable bound, as well as the relations between robust stable bound and the solution of Riccati matrix equation, are studied for a class of systems with nonlinear disturbance. The robust stable bound of control systems is optimized with constraints of closed loop poles. Related optimization algorithms are also presented based on the parametric solution to the LQ inverse problem.
