混合控制系统及其分析与设计方法

DESIGN AND ANALYSIS OF HYBRID CONTROL SYSTEMS

混合控制系统是指那些由实时决策子系统和实时数值反馈子系统组成的系统，这类系统的特点是事件变量和时间变量的演化在不同子系统内并行、实时地进行．本文基于对混合控制系统以往研究框架的分析，给出了混合控制系统的一个新框架，并提出了混合动态系统的分析和设计方法．混合控制系统的设计包括系统性能指标的分解、决策子系统的设计和实时数值反馈子系统的设计，其分析则分为离散时间域和离散事件域分析．文中采用了煤气炉系统作为例子说明所提出的混合控制系统的框架和分析、设计方法．

Hybrid control systems are those systems that combine real time decision-making components and real time numerical feedback control loops. These systems are characterized by their parallel evolution of event variables and time variables in real time at their different abstract levels.This paper is devoted to present a new framework of hybrid control systems, and their design and analysis approaches which are consistent with the proposed framework. The design approach consists of decomposition of system performance specifications, design of discrete event driven decision-maker and design of real time feedback control loops. The analysis approach consists of analysis of time numerical domain and discrete event domain. A gas burner system is systematically designed and analysed to show the advantages of the approaches.
