Abstract :
The current-controlled voltage-source-inverter-fed interior permanent-magnet synchronous motor (IPMSM) has received widespread interest in high-precision industrial drive applications. This paper presents a detailed comparison of various current controller schemes, particularly hysteresis and ramp comparator controllers for the IPMSM drive based on performance at different speeds. The hysteresis and the ramp comparator controllers are getting more attention due to their simplicity and high dynamic responses. In this paper, fixed, sinusoidal, and mixed-band hysteresis current controllers, as well as conventional ramp and improved ramp comparator controllers, are considered. The harmonic spectra of the motor line currents for various current controllers are obtained using a fast Fourier transform for comparison purposes. The comparison is based on experimental results. In order to compare the performance of various controllers, the complete drive system is implemented in real time using the digital signal processor controller board DS-1102.
