| 中文摘要 |
| 模型降阶作为简化大规模系统的重要工具,一直受到控制界的高度重视.另外,由于在$H_\infty$ 理论指导下所设计的控制器具有维数过高的特点,这将导致控制器的实现和维护受到限制.基于此本文提出了一种平均驻留时间切换离散线性系统降阶输出反馈控制策略.该策略由一个降阶的切换输出反馈控制器和一个对切换控制器在每个切换时刻的状态执行复位规则的监控器组成,该控制器对切换控制器在每个切换时刻的状态进行降阶控制.仿真结果验证了该方法的有效性. |
| 英文摘要 |
| Model reduction has been highly valued for the control field to simplify large-scale systems. In addition, under the guidance of $H_\infty$ theory the controller designed has the characteristic of too high dimension, the realization and maintenance of the controller will be restricted. Based on this, a reduced order output feedback control strategy for discrete linear systems with average dwell time switching is proposed. The strategy consists of a reduced order switching output feedback controller and a monitor that performs reset rules for the switching controller at each switching time. The controller performs reduced order control on the state of the switching controller at each switching time. Simulation results show the effectiveness of the method. |
