摘 要：By the analysis of operation mechanism of Brushless DC motor（BLDC）,the electric braking mathematical model of BLDC with full bridge modulation is set up,and in combination with dynamic characteristics during electric braking,the simulation model of motor braking in electric vehicle is established in Matlab/*** control strategy is adopted in the system,and braking current is controlled by adjusting duty cycle to keep the slip rate within ideal *** simulation results show that the ABS based on motor braking can be realized by adopting fuzzy control strategy,and the system is stable,with better static and dynamic characteristics.
