对于具有非线性摄动的离散系统 ,提出了H∞ 鲁棒控制问题 .应用离散系统H∞ 范数与Riccat不等式的关系 ,给出了考虑具有不确定非线性摄动离散系统的H∞ 鲁棒性能设计准则 ,以此 ,给出了对于这样的被控对象的反馈控制器设计方法 . For discrete systems with nonlinear perturbation, a robust H∞ control problem is proposed. By using the relation between H∞ norm and Riccat inequality for discrete systems, the robust H∞ robust system with uncertain nonlinear perturbed discrete systems Performance design criteria, in order to give a feedback controller design method for such a controlled object.
