Design of the PLC On-Line Optimization Pi Controller Parameters Based on Fuzzy Algorithm

Abstract:

With the development of science and technology, the controller is widely used in various fields, and control performance is also more and more accurate. In recent years, PID technology is thorough research discuss in many fields, and PID are still not thoroughly solved in online and offline optimization problems. Based on this, this paper introduces the PI controller from the two aspect of the parameter design and online optimization, and the introduction of a new method-fuzzy algorithm, to solve the on-line optimization problem of PI controller parameters in the process of PLC designing, and the program is brought into MATLAB software simulation, to prove the correctness of the program. Finally, this paper presents PI controller with some deficiencies, and provides theory reference for the PI controller parameters optimization.
