误差方差及极点配置区约束下输出反馈控制器设计

Dynamic Output Feedback Controller Design for Continuous Systems with Variance and Regional Pole Constraints

在控制系统中，其稳态状态方差和闭环极点是表征系统稳态及暂态性能的2个重要指标。一个理想的工程控制系统除了需具有良好的稳态特性外，还需要具有良好的暂态性能以保证过渡过程的品质要求。协方差控制理论在兼顾系统暂、稳态性能指标要求的应用中具有良好的实用效果。该文讨论连续系统在误差方差以及闭环极点配置区约束下，动态系统输出反馈控制器的设计问题，通过对反馈增益阵G的研究分析，给出了此类控制器的存在条件及相关性质。

In the control systems, the steady state variance and dosed-loop poles are the two important properties which show ihe 3teady and transient performance of the systems. A well control system should include both good steady and transient characters. Covariance control theory had been proved to be effective to the above problem. In this paper, the design of dynamic output feedback controller for continuous with variance and regional pole placement is considered, in accordance with an algebric equation, the authors study and develop the existence and the solution of the controllers.
