基于Jitterbug的網(wǎng)絡(luò)控制系統(tǒng)時延補(bǔ)償?shù)难芯?/h1>

目前控制系統(tǒng)調(diào)度策略和控制性能兩者的最優(yōu)化是一個難題。由瑞典Lund 學(xué)院開發(fā)
的Jitterbug 工具箱，提供了一個分析網(wǎng)絡(luò)控制系統(tǒng)時延的平臺，可以對各種時延情況下的線性閉環(huán)控制系統(tǒng)提供靜態(tài)的性能預(yù)估分析。本文基于Jitterbug 內(nèi)部模塊特性，利用其特定的調(diào)度策略和性能指標(biāo)函數(shù)，針對一類網(wǎng)絡(luò)控制系統(tǒng)，導(dǎo)出了該實時閉環(huán)控制系統(tǒng)的性能優(yōu)化時延需求，并進(jìn)行了時延補(bǔ)償分析。

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.
