In order to complete the drive control of electric vehicle better,a drive control method for electric vehi-cle with high resolution laser encoder is proposed.The high-resolution laser encoder is used to collect the operation re-lated input signals of the electric vehicle drive system.The improved particle swarm optimization algorithm is used to preprocess all signals,identify all undetermined parameters in the model,and correct the amplitude deviation and or-thogonality deviation of the signal.The equivalent average value model is constructed to analyze the influence of the e-lectric vehicle drive system on the zero-sequence circulation.The PID control and fuzzy PID control are effectively combined to establish the electric vehicle drive controller,and then the electric vehicle drive control is completed.The experimental results show that the proposed method can achieve good driving control effect of electric vehicles.
