基于模糊PID控制的变速器加载控制系统的仿真研究

Simulation of Transmission Loading Controller Based on Fuzzy-PID Control

随着变速器加载控制技术的发展,常规PID控制器已经不能满足对变速器加载运行时的动态和静态性能要求。本研究分析了变速器加载控制系统的结构原理,设计了模糊PID-PI双闭环控制器对变速器进行加载控制,并运用S imu link分别对模糊PID-PI控制器和常规PID-PI控制器进行了仿真。结果表明,模糊PID-PI控制器具有更好的控制特性。

With the development of transmission loading technology,routine PID controller could not satisfy the requirement of systemic dynamic and static performances of transmission loading.In this paper,it analyzes the principle of transmission loading system,and the application of the fuzzy-PID controller and routine PID controller in transmission loading system are studied with Simulink.The results show that the fuzzy PID-PI controller has a better control performance.
