Design of Motor Controller New Energy Vehicle Based on DSP

For the AC Induction Motor (ACIM) has the characteristics of simple structure, high power factor and high overload rate, the drive controller of the new energy vehicle induction motor is researched and designed. According to the d-q axis coefficient model of induction motor, the controller model of induction motor based on vector control is constructed. The controller consists of Digital Signal Processor (DSP) TMS320F28035, power drive circuit, control circuit and current detection circuit. The digital signal processor (DSP) TMS320F28035 produced by TI is the core of the whole control system. With the help of more precise digital vector field oriented control (FOC) algorithm, DSP enhanced PWM (EPWM) module is used to generate high precision flexible space vector pulse width modulation (SVPWM) signal this allows the motor to maintain high efficiency over a wide range of speeds.
