多模态PID控制器

A Multi-Mode PID Controller

本文遵循“综合即创造”,将人工智能技术与传统PID控制相结合,集各种控制方法之长,形成一种P、I、D功能完全分离,具有开环与闭环、负反馈与正反馈结合的多模态PID控制。具有最优控制品质和极强的鲁棒性、结构简单、通用性强、使用调整方便。

This paper attempts to show how through the use of artifcialintelligence techniques together with some novel ideas about making use ofconventional PID control,adaptive control,robust control and variable struct-ure control etc,an innovated multi-mode PID controller(M-PID)with separ-ate functions of the P.I and D modes,combined modes of open and closed loopcontrol,and combined modes of positive and negative feedback control etc.,couldbe built.The control performances of the control system formed by such aninnovated M-PID controller are optimal,and its robustness is strong. Simulation results on comparative basis show that the M-PID controllerinnovated in this paper is powerful technique promising wide applicability inautomatic control practice.
