Abstract

This paper presents a study on the DSP (Digital Signal Processor) controller for the PBW (power-by-wire) system using BLDC (Brushless Direct Current) servo motor pump. The PBW hydraulic actuator was realized with hydraulic pump driven by BLDC servo motor, hydraulic cylinder and controller. This PBW system needs speed control of servo motor for linear thrust action of hydraulic cylinder. This paper implements a servo controller with vector control algorithm and MIN-MAX PWM technique. As CPU of a controller, TMS320F2812 DSP was adopted because it has PWM waveform generator, A/D converter, SPI (Serial Peripheral Interface) port and many input/output port etc.
