Control of variable speed drive (VSD) based on diode clamped multilevel inverter using direct torque control and fuzzy logic

The deployment of Direct Torque Control using fuzzy logic in variable speed drive that is based on multilevel inverter has increased by researchers in the last few years. A fuzzy logic in variable speed drive as type of controlling will be employed to control the speed and torque of industrial applications. Our proposed approach is based on Simulator (MATLAB/SIMULINK) that is used to identify the performance of Direct Torque Control in terms of Speed, Torque, Transient response and the current ripple. The goals are to reduce the overall current ripple and, hence to improve the transient response.
