由于网络化控制系统分析与设计的复杂性,其控制与通信协同设计问题一直没有得到解决。该文讨论了一类离散线性时不变网络化控制系统在服从介质访问约束和传感器一控制器端存在Markov随机延迟的情况下控制与通信协同设计问题,提出了系统均方稳定的条件。采用静态通信序列,使通信序列和控制器可以分别设计,应用V-K迭代算法设计最优周期控制增益。仿真算例验证了系统在所设计的最优控制器下达到均方稳定。
Due to the complexity of networked control system analysis and design, the problem of collaborative design of control and communication has not been solved. In this paper, the control and communication collaborative design of a class of discrete-time linear invariant networked control systems subject to medium access constraints and Markov random delays at the sensor-controller side are discussed. The condition of the mean-square stability of the system is also proposed. The static communication sequence is adopted so that the communication sequence and the controller can be designed separately. The V-K iterative algorithm is used to design the optimal periodic control gain. Simulation results show that the system achieves mean square stability under the optimal controller.
