Servo system design and implementation based on position and speed control for the linear motor

Based on TI' s chip DRV8312 to realize the speed and position control for linear motor. The driving circuit principle based on DRV8312 to introduce the system composition and the hardware design, through the DSP software programming to realize the fast servo control for linear motor. The program setting and Hall signal verification, the inverter circuit and the back EMF validation, PWM duty ratio and speed response experiments proved that the proposed scheme is realizable and reliable.
