四种先进PID控制方法及性能比较
Four Kinds of Advanced PID Control Methods and Comparison of Their Performance
摘要
Abstract
As the parameters of classical PID is fixed, the application areas are limited. For above reson, four kinds of advanced PID control methods are researched. On the base of classical PID,fuzzy technique, vague technique and Genetic Algorithms are respectively introduced so as to put forward control methods of Fuzzy-PID, Vague-PID, GA-Fuzzy-PID, GA-Vague-PID and their performance is compared as well. On the base of classical PID, intelligent technique is introduced so as to timely online adjust the three parameters of classical PID, which forms self-adaptive PID. Because Fuzzy control possesses excellent roburst and decouplity and doesn't have strict demand for the model's precision of the objects under control, it can make up of Fuzzy-PID; measures of similarity reasoning using vague sets are close to practice and easy to obtain control a-mount,so it can make of Vague-PID; fuzzy inference rules can be optimized by the genetic algorithm,so it can make up of GA-Fuzzy-PID and GA-Vague-PID. The above four kinds of self-adaptive PID control methods are designed in the paper. A-nalysis and comparison are given in theory, and each advantage and disadvantages are pointed out. The simulation results show that the above self-adaptive PID control methods have a quicker rise time and a more fast response speed than classical PID and the methods introduced into GA have a quicker rise time and a more fast response speed than not.关键词
