【Abstract】 The load of electric vehicles used for sites is changeable,and the traffic environment is complex.In order to improve the response speed of the electric vehicle and anti-jamming capability,an improved genetic BP neural Network(IGA-IBP)algorithm is proposed to reduce the torque ripple and extend the travel distance of the electric vehicles.Based on the proposed algorithm,aparameter self-learning PID controller is designed and applied to the driving system of the electric vehicle.The analysis results show that the IGAIBP algorithm,compared with the traditional GA-BP,has the advantages that the electric vehicle has faster speed response,more anti-disturbance ability,and smaller motor torque ripple.Therefore,our algorithm can reduce the vehicle driving noise,increase the driving comfort,and extend the travel distance of the electric vehicles,thus playing an important role in the promotion and application of the electric field.更多还原
