Abstract

This paper proposes a highly-integrated and digitized servo control system for permanent magnet synchronous machine (PMSM) used in radar-driven system, which is based on application specific intelligent power module (ASIPM), digital signal processor (DSP) and complex programmable logic device (CPLD). The field oriented control (FOC) algorithm and space vector pulse width modulation (SVPWM) technique are implemented in the system. The new generation of power module ASIPM is adopted to achieve high integration, small size and low cost of the system. The DSP completes all the real-time signal sampling, processing, transformation and computation. The CPLD is utilized as a complement to DSP to address the functionality of logic signal processing like signal conditioning and fault detection. The performance of the system is verified experimentally.
