摘要
基于Lyapunov-Krasovskii稳定性定理,采用采样控制方法,研究具有时滞的网络化牵引控制系统H∞控制问题。利用闭环泛函方法,构造新的包含更多采样点信息的Lyapunov-Krasovskii泛函,从而获得具有更小保守性的稳定性判据。随后,将此判据拓展到含有外部输入以及参数不确定的网络化牵引控制系统中,并给出H∞采样控制器求解方法。实例仿真结果表明:所得H∞控制器能使牵引电机模型状态趋于稳定,说明该求解方法有效的。
Based on the Lyapunov-Krasovskii stability theorem,the H∞control problem of networked traction control system with time delay was studied by sampled-data control approach.By constructing new Lyapunov-Krasovskii functional with loop-functional approach which contains more information of sampling points.A less conservative stability criterion was obtained.Then,the criterion was extended to the network control system with external inputs and uncertain parameter,and the H∞sampling controller was derived.Finally,in simulink examples,the obtained controller can make the states of networked traction control system stable,which proves that the method is feasible.
