摘要
采用动态观测器,考虑同时带有网络诱导随机时延和信号量化的网络控制问题。其中信号经网络从传感器到控制器和从控制器到执行器的传输中存在通信诱导随机时延,并采用动态量化器量化信号。设计控制器的同时,提出量化的控制策略,使得闭环系统在量化器的量化范围条件下指数均方稳定且具有指定的H_∞性能指标。通过数值仿真例子表明设计方法的有效性。
In this paper, the dynamic observe-based H∞ control problem for networked control systems with quantization and random delay is discussed. The random delay from the sensor to the controller and from the controller to the actuator is considered. The quantizer considered here is dynamic. The method of controller design is given and a quantized H∞ control strategy is derived with a condition on the quantization range, such that the closed-loop system with quantization and random delays is exponentially mean-square stable and has a prescribed H∞ performance bound. An example is presented to illustrate the effectiveness of the proposed method.
