摘要
针对T S模糊模型描述的一类不确定非线性连续系统,研究使得闭环系统的稳态方差小于某个给定上界,同时闭环极点位于给定圆盘中的状态反馈鲁棒方差控制律设计问题。导出了以一组线性矩阵不等式表示控制律的存在条件。通过一个质量弹簧阻尼控制系统验证了这种方法的有效性。
The design problem of the state feedback robust variance controllers which guarantee the closed-loop poles in a specified disk and steady-state variance less than a given upper bound is concerned for a class of nonlinear systems with uncertainties based on T-S fuzzy model. Conditions for the existence of such controllers are derived. Finally, a simple example of mass-spring-damping control system is given to illustrate the results.
