基于状态增广方法的网络化PI控制及其应用
发布时间：2022-12-11 20:37
网络化控制系统（NCS）是将通讯网络引入到传统控制系统实现系统元件间信息交互的一类先进控制系统,具有低成本、易维护、信息共享和远程控制等优点,已经被广泛应用于诸多现代工业控制系统。同时,通讯网络引入的网络诱导因素（如网络时延和数据丢包等）直接影响系统的稳定性和性能,给系统的分析和综合带来了新的挑战。一些传统控制理论（如比例积分（PI）控制、模糊控制等）可能不再适用于NCS,亟待重新深入研究。本文将考虑网络通讯过程中时延和数据丢包等因素,采用状态增广方法研究如下三类问题:（i）一类连续线性系统的网络化PI控制问题及其在无线网络环境下轮边驱动系统（DDW）车身调高的应用;（ii）一类具有常值输入和时变采样的连续线性系统的网络化输出跟踪控制问题及其在DDW速度跟踪的应用;（iii）一类具有传感器饱和和测量噪声的离散非线性系统的网络化模糊静态输出反馈控制问题。具体研究内容如下:（i）同时考虑网络诱导时延和随机数据包丢失,通过引入两种不同的输入时延状态分别刻画比例和积分控制输入,利用状态增广方法建立带有两个输入时延的连续时间方程与脉冲时刻重置方程的随机脉冲时滞系统。针对该系统,构造包含不连续项以...
