ANTI-JERK CONTROL METHOD AND SYSTEM FOR ELECTRIC CAR

摘要

PROBLEM TO BE SOLVED: To provide an anti-jerk control method and a system for reducing vibration of an electric car using power of a motor.SOLUTION: An anti-jerk control method for an electric car using power of a motor comprises the steps of: calculating actual speed of the motor; calculating model speed of the motor; determining vibrational components based on a deviation between the calculated model speed and the calculated actual speed of the motor; performing high frequency filtering of the vibrational components for the purpose of eliminating error components included in the vibrational components; performing phase delay of the filtered vibrational components by a set time for the purpose of compensating phase lead occurred during high frequency filtering; and applying a set gain value to the phase-delayed vibrational components by a set time thereby generating an anti-jerk compensation torque.
