Modular learning laboratory of AC servo drive

This paper presents an implementation of learning laboratory of AC servo drive using the eZdsptrade F2812 digital signal processor (DSP) for undergraduate senior students. Since the electric motor drive is an interdisciplinary course, the students need to sufficiently know several backgrounds such as machines, digital control system, programming, and power electronics. Therefore, the learning laboratory is intended to design both hardware and software as modules. So students would easily learn the hardware implementation of overall system circuit by circuit. Similarly, codes of each functional block are well defined and written by using object oriented programming (OOP) concept. As a result, students can clearly understand the complex control of permanent magnet synchronous motor (PMSM) using quadrature encoder pulse (QEP), known as AC servo drive. In this paper, the details of modular hardware and software aspects will be presented along with the experimental results.
