Abstract

Compared to traditional digital power converter system design, model-based design can significantly improve the development efficiency by using graphical modeling and simulation. This chapter describes a workflow that applies model-based design to develop a digital power control system for a half-bridge converter based on DSP TMS320F2812. In this workflow, the control loop of the converter is closely analyzed and reconstructed at the beginning. A DC/DC simulation model and fixed-point fuzzy PID controller model are then established. Combined with Matlab/Embedded Coder, peripheral drivers, as well as the asynchronous scheduler, are integrated, and the production-quality C code of the controller is also generated. Finally, the code is compiled and verified through software-in-the-loop (SIL) and processor-in-the-loop (PIL) testing. The result shows the efficiency of developing a digital power converter with model-based design.
