A Research on the Fuzzy-self Adjusting PID Speed Ratio Control System for Metal V-belt Continuously Variable Transmission

针对汽车金属带式无级变速器速比控制的特殊要求,结合PID控制和模糊控制各自的优点,设计了自调整模糊PID速比控制系统,并建立了基于Matlab/Simulink的CVT整车仿真平台,通过仿真验证了自调整模糊PID速比控制能够很好地跟踪目标速比,具有良好的动态响应和较高的稳态控制精度。

Aiming at the special requirements of vehicle metal v-belt continuously variable transmission ratio control,the fuzzy-self adjusting PID speed ratio control system combining the advantages of both PID and fuzzy control is designed.And a CVT vehicle simulation platform is established by Matlab/Simulink.Through the simulation by this method,the results show that the fuzzy-self adjusting PID speed ratio control can track the target speed ratio well and has a good dynamic response and high control accuracy of steady state.
