DSP-Based Control of Autonomous Vehicle Driven PMDC Motor

Abstract: In this paper a direct current (DC) motor drive system for a vehicle tracking a given route is developed. The control of the system is performed using TMS320F2808 digital signal processor (DSP). The algorithm, which is used for DC motor control, is designed using Matlab/Simulink simulation software. The generated codes are built into the TMS320F2808 directly via CCS (Code Composer Studio) by favour of this software.
A permanent magnet DC (PMDC) motor is used in the vehicle. Motor control is performed based on digital signal controller. The H-bridge dc-dc converter which is driven by the pulse-width modulation (PWM) signals generated by micro controller changes the average value of the voltage applied to the motor and as a result the speed of the motor is controlled
