PIDT (proportion integration differentiation template) control technology and method with optional control template

Abstract

The invention discloses a PIDT (proportion integration differentiation template) control technology and method with an optional control template. The PIDT control technology comprises PID (proportion integration differentiation) control and template control. By the template control, the dynamic response performance of a system is improved. In the process of the PID control, a set of control parameters are difficult to adapt to a starting process when a large deviation occurs, and to a work process when a small deviation occurs at the same time, because the contradiction between a response speed and a overshoot quantity exists. The main method of the PIDT control technology comprises the following steps of: in the process of controlling the system to start (the deviation is relatively large), using the template (T) to independently control or using the PID and the template (T) to jointly control, wherein the controlled quantity of the template is determined by the selected template and the template control strength factor; in the process of working, when the deviation is small, using the PID control, when the deviation is more than a certain value, invoking the template control; and when the deviations are different, selecting different template control coefficients, wherein the action time of the template control at every time is limited. In the PIDT controller with the optional control template, not only a built control template is for use, but also the template can be individually built according to the control rule.

Description

technical field [0001] The invention belongs to the field of intelligent control or industrial control, and in particular relates to a controller, a control technology of a control system and a control method thereof. . Background technique [0002] In engineering practice, the most widely used regulator control law is proportional, integral, differential control, referred to as PID control, also known as PID regulation. PID controller has become one of the main technologies of industrial control because of its simple structure, good stability and reliable operation. [0003] In some complex and high-precision control systems, the effect of PID control may not be particularly ideal, such as the contradiction between the adjustment time and the overshoot, and the difficulty in debugging. People continue to explore new control strategies, such as fuzzy control ( Fuzzy Control), Neuron Control, etc. There are more and more control strategies derived from PID control algorith...
