Design of a DSP Controller and Driver for the Power-by-wire(PBW) Driving System Using BLDC Servo Motor Pump

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.

Stable Rules Definition for Fuzzy TS Speed Controller Implemented for BLDC Motor

“…Due to the constantly increasing interest in ARM processors, manufacturers offer BLDC motor controllers in the form of dedicated shields [24]. Additionally, demanding applications are often handled by modern digital signal processors, which are a convenient way to run a variety of advanced algorithms [25][26][27]. The most sophisticated implementations (e.g., BLDC neural speed controllers) are often executed with the use of parallel computing ensured by field-programable gate array (FPGA) modules [28][29][30].…”
