论PID与自耦PID控制理论方法

On control theory of PID and auto-coupling PID

PID增益鲁棒性差的突出问题引起了作者质疑PID控制理论的动机,提出了自耦PID协同控制理论方法,意外解决了PID增益鲁棒性差与抗扰动鲁棒性差的科学问题,形成了前期研究成果.然而,前期成果没有科学阐明自耦PID控制律及其整定规则的理论依据,没有科学揭示PID潜在的基础理论问题.为此,本文通过PID控制系统的物理属性分析,首次揭示了PID御用概念会引起量纲冲突与不协调控制机理两个矛盾,提出了解决这两个矛盾的科学设想.本文研究不仅阐明了纠错PID御用概念的必要性和迫切性,科学解释了自耦PID控制律及其整定规则的理论依据,而且开创了遵循量纲匹配原则的控制理论发展方向,具有重要科学意义.

The prominent problem for poor robustness of PID gains has caused the author to question the PID control theory,and proposed the cooperative control theory method of auto-coupling PID(ACPID),which accidentally solved the scientific problem of poor robustness of PID gain and poor robustness of anti-disturbance,and formed the early research results.However,the previous achievements did not scientifically clarify the theoretical basis of the ACPID control law and its setting rules,and did not scientifically reveal the underlying theoretical problems of PID.Therefore,through the physical attribute analysis of PID control system,this paper revealed for the first time the two contradictions of dimension conflict and discordant control mechanism caused by the PID imperial concept,and proposed the scientific assumption to solve these two contradictions.This paper not only clarified the necessity and urgency to correct the PID imperial concept,scientifically explained the theoretical basis of the ACPID control law and its setting rules,but also created the development direction of the control theory following the principle of dimensional matching,which has important scientific significance.
