Simulation and Experimental Research of Hydraulic Actuator for Automatic Transmission

Abstract:

The accurate control of hydraulic actuator is critical for automatic transmission to launch or shift smoothly. The mathematical and simulation model of proportional flow valve based on Matlab/Simulink were established , and hydraulic actuator control arithmetic based on NNPC(Neuro Network Predictive Control) was introduced to realize accurate control of clutch displacement. The experiment was carried out and the rusults showed that the model of proportional flow valve was correct and hydraulic actuator intelligent control algorithm based on NNPC had good adaptive ability and high precision.
