控制理论与计算机实时控制

本文在综合论述系统理论各学派的形成和其基本论点的基础上,推荐一种按层次概括各种理论的方法;对当前计算机控制系统的发展趋势——分散型综合控制系统,从系统分解与协调的角度阐述其合理性;并且结合计算机的发展过程说明现代控制理论是计算机控制的理论基础;最后,文章推荐几种有发展前景的微机实时控制方案,即模型预测启发控制、模型参考自适应控制和模糊控制,它们共同的特点是,不需要对被控对象精确建模,控制质量优于 PID 控制以及便于用微机实现。

Contol Theory and Computer Real Time Control

There are different classifications of system theory now in the literature based on the survey of the point of view for scholars,an approach to the study of the systems theory in levels is proposed.By means of the decomposite and concordant principle,the development trend towards total distributed control systems is discussed.It also shows that the modern control theory is the theoretical foundation of the computer control. Finally,several fascinating control sschemes,Model Predictive Heuristic Control,Model Reference Adaptive Control and Fussy Control for microcomputers in real time are given.Their general features are:being unnecessary for an exact mathematical model, having better performance than PID and being easily realized with microcomputers.
