A Study of 1MHz Multisampling Deadbeat Control for Low Carrier Frequency PMSM Drive System

EVs (Electric Vehicles) and HEVs (Hybrid Electric Vehicles) have electric motor drive system, and its quick and smooth response is one of advantage in electric motor drive system. In order to utilize potential performance of control response, this paper introduces MSDB (Multi Sampling Deadbeat control) of PMSM (Permanent Magnet Synchronous Motor) drive system for EVs and HEVs using a FPGA (Field Programmable Gate Array). The proposed deadbeat control using a FPGA can realize good response and robustness, especially for electric motor drive system using low carrier frequency of PWM (Pulse Width Modulation) inverter like as EVs and HEVs.
