FPGA-Based Hysteresis Current Control for Induction Motor fed by a Voltage-Source Inverter

This paper discusses FPGA implementation of the hysteresis current control strategy for an induction motor. The hysteresis control method is an on-off closed-loop strategy that has been used for a long time. What makes this control method interesting is the simplicity of the digital control application and the effortless design steps. This paper discusses implementing the hysteresis current control method using an FPGA. The closed-loop implementation is performed using Cyclone IV FPGA, and a detailed experimental study is carried out to evaluate the system’s performance. The hysteresis current control strategy is investigated under steady-state and transient conditions.
