Soft Starting of Three-Phase Induction Motor Using DSP Auto Coding and Power System Controllers (Digital Motor Controllers)

Abstract

Since the rapid development of the digital controller, such as Micro-Controllers (MC) and Digital Signal Processor (DSP), to replace the traditional analogue controller, their applications in the power system control are growing in fast pace. Several algorithms have been developed to achieve the best utilization of the digital controller. This is considered a major barrier facing the power engineers. Auto coding is a term used to express the translation of the high level model, which power engineer are familiar with, to a low level assembly code targeting a specific controller. In this paper, the authors present their experience dealing with the auto coding tools from MatLab targeting Digital Signal Processor (C2000 Family). Moreover, this paper walks through the steps and the most famous mistakes for converting the power system MatLab model to an assembly code for the DSP-C2000. The paper is using an induction motor controller as an example along with the practical laboratory results.
