摘要: 针对网络控制系统存在不确定短时延情况,提出了一种基于控制性能优化的网络化控制器优化设计方法,该方法利用控制性能梯度优化来得到网络化控制器参数,避免了依据Lyapunov稳定性理论和线性矩阵不等式(LMI)进行网络化控制系统(NCSs)设计时出现变量个数大于约束不等式个数的情况。通过对水下航行器航向控制系统的仿真研究,表明了该方法的可行性和有效性。

Abstract: An optimizing design method for NCSs is presented to solve this kind of problems in the design of common NCSs controller with clockdriven sensors, eventdriven controllers and actuators. In the design of networked control systems (NCSs) based on Lyapunov stability theory and linear matrix inequality (LMI), the number of variables in LMI often exceeds the number of LMI constraints, which may present the difficulty in solving the parameters of controller. The optimal controller parameters can be found on the basis of the gradient optimization. The simulation results show the effectiveness of the present method for UUV heading control system.

Key words: control science and technology, navigation and control technology, optimal control, nonlinearity
