基于模糊PID控制策略的液压缸试验台加载系统设计
Design of loading system for hydraulic cylinder test-bed based on fuzzy PID control strategy
摘要
Abstract
The loading system of a hydraulic cylinder comprehensive performance test-bed is taken as the research object in this paper and a loading control method based on fuzzy proportional integral differential( PID) control strategy is proposed to solve the problem that the loading system is unstable and inaccurate due to the external interference. Firstly,the joint model of displacement system and loading system is obtained according to the structural characteristics of the test-bed and the theory of passive control. The influencing factors of the control precision are obtained by using MATLAB to simulate its output loading force under the influence of the displacement system. By adding the fuzzy PID control strategy to the original system, it can adjust its PID control parameters dynamically, effectively improve the response speed of loading force,and shorten the response time.关键词
