| 摘 要： | 基于无因果划的键图模型,提出一种不需对象精确数学模型的定性、定量混合控制新方法,为精确信息控制与定性控制相结合提供了一个可行方案。首先应用键图理论,建立系统无因果划键图模型,并给出其相应环节的定性方程;然后详细阐述系统不含定量信息和包含定量精确信息的两种定性控制方程及推导过程。仿真结果证实,此算法有良好控制品质。对比传统PID控制,此算法有好的动态性能、鲁棒性和跟踪特性,可控制非线性时变对象,且控制方程简单易于实现。

| Abstract: | Based on bond graph theory without causality, a hybrid qualitative and quantitative control method which needs no accurate math model is presented. It provides an approach to combine the control of accurate information with quantitative control. The bond graph model without causality is built and the qualitative representations are given. The control equations with or without quantitative value are deduced. Comparing with PID, the algorithm has better transient performance and robust. It is suitable to control the nonlinear, time-varying plant. |
