Abstract:For the extended range electric vehicle, the vehicle speed may fluctuate due to the uncertainty of road disturbances. In view of this problem, an adaptive robust vehicle speed tracking controller is designed to enable the extended range electric vehicle speed to track the ideal value. The validity of the algorithm of the designed adaptive controller is verified by Matlab / Simulink simulation software. Simulation results show that the controller can adaptively adjust the control gain, and has good robustness against the uncertainty of unknown road surface environment disturbance. The simulated results can provide a reference for the design of speed tracking control of rangeextended electric vehicles.
Keywords:extended range electric vehicle; vehicle speed control; uncertainty; adaptive control
