Adaptive Control Research Based On Differential Drive Active Steering Of Electric Vehicle

In order to prevent the four-wheel independent drive electric tricycle in differential drive active steering to understeer or oversteering. It is necessary to control the vehicle, thus setting up four degrees of freedom vehicle model and using the MRAC control strategy to control vehicle. Using simulink software set up the electric wheel vehicle control model and simulate the model so as to analysis single input quantity before and after the control effects on a single output. The simulink simulation show that the electric tricycle can quickly reach the stable state under the adaptive control, transient response quality is good, and the system has strong adaptive ability and robustness.
