Abstract

The invention discloses a method for realizing a fuzzy PID (Proportion Integration Differentiation) ActiveX control. The method comprises the following steps of: 1, setting a variable, a membership function of the variable, a fuzzy reasoning method and a de-fuzziness method; 2, setting a reasoning rule, determining the fuzzy values of e and ec to obtain accurate values kp, ki and kd after de-fuzzing a PID output variable, and establishing a fuzzy control decision polling list; and 3, compiling a fuzzy PID algorithm through VB (Visual Basic), and creating an ActiveX control. Due to the adoption of the control realizing method disclosed by the invention, the logical operation program of a fuzzy reasoning process is not required to be compiled any more during development, the output values deltaKP, deltaKI and deltakd of the fuzzy adjustment amount of a PID parameter which corresponds to a basic discourse domain are not required to be calculated according to a weighted average method, a program structure is simplified, the program executing period is shortened greatly, and the response speed of a system is increased.

Description

technical field [0001] The invention relates to a method for realizing a fuzzy PID algorithm Active X control, and belongs to the technical field of realization and application of advanced control methods. Background technique [0002] The Active X control triggers the control operation through events (click control, keyboard input, etc.), the method and property provide the input and output interface used by the control container, and use the protocol support of the configuration software for the Windows standard ActiveX control to realize The data connection between the algorithm module and the configuration interface makes it easy to call the control algorithm. [0003] As an advanced intelligent control algorithm, the fuzzy PID algorithm has the advantages of no need to establish a mathematical model of the controlled object compared with the conventional PID control, and has certain adaptability to the time delay, nonlinearity and time-varying nature of the controlled o...
