DSP Based Controller for Battery Charging System

摘要

The paper presents a digital control application, for an automotive battery charging system, using a Digital Signal Processor (DSP) from Texas Instruments (TI). The system to be modelled is an automotive alternator. The application runs on a TMS320F2812 DSP. Once the desired functionality has been captured and simulated, using MATLAB/Simulink/Embedded Target for TI C2000 DSP environment can be generated code for the DSP. All task assignments to processor are automatically made by the software. Adaptive system identification is used for determining the mathematical model of the alternator. A control algorithm is implemented in order to control the output voltage of the alternator.
