目前控制系统调度策略和控制性能两者的最优化是一个难题。由瑞典Lund 学院开发 的Jitterbug 工具箱,提供了一个分析网络控制系统时延的平台,可以对各种时延情况下的线性闭环控制系统提供静态的性能预估分析。本文基于Jitterbug 内部模块特性,利用其特定的调度策略和性能指标函数,针对一类网络控制系统,导出了该实时闭环控制系统的性能优化时延需求,并进行了时延补偿分析。 关键词:Jitterbug;预估分析;代价函数;时延补偿;网络控制系统 Abstract: Currently combining scheduling attributes with control performance optimization is a difficult issue. Developed by Lund institute, the toolbox Jitterbug allows the user to setup a platform analyzing the induced delay of networked control system by using a quadratic performance criterion. The tool can also evaluate the stationary behavior of a linear system under various timing conditions. Based on the internal model of Jitterbug and its certain scheduling attributes with the quadratic cost function for a class of networked control system, we have derived the delay requirements of real-time closed loop control system and proceeded with analysis of delay compensation.
