Level Control System Expert PID Control and Simulation
Abstract
Level control is common in industrial production controlled object is a nonlinear inertial system that has important applications in the process of production. In today's society of industrial production, the level is also an important indicator, because both in everyday life and in modern industrial production, the number of devices or some means can be reduced to a basic level control, level experimental device can effectively analog production site, simplifying the process control, the process can be flexibly configured to implement different control schemes. With the rapid development of science and technology, using the traditional PID control level has been gradually unable to meet the needs of social production, and the development of control science, artificial intelligence technology becomes more mature and widely used in modern production control. The combination of artificial intelligence and traditional PID will combine the advantages of both, better control effect, mainly fuzzy PID, neural PID, and expert PID control.
In this paper, double - tank liquid level control study, overall hardware structure of the double - tank, system modeling, expert PID control algorithm, and gives a detailed dynamic simulation study. The actual object of mathematical modeling, and model parameters determined, here is the step response method. In addition, this article will focus on the PID control algorithm and intelligent control expert system, expert PID controller design, and finally test the feasibility and accuracy of using simulation technology, here we use the MATLAB software simulation.
