Fuzzy-Direct Torque Control of The Squirrel-Cage Motor Fed on The PEMFC Fuel Cell System: Design and Simulation

In this paper, we present the fuzzy logic control (FLC) applied to the direct torque control (DTC) of the asynchronous machines in a fuel cell system. Using the FLC and PI controllers, we studied the response of the asynchronous motor at a variable reference speed and charge. Subsequently, we introduce the principles of control of fuzzy logic by justifying our choice of this method to control asynchronous machines. To confirm its efficiency, we use a simulation under several operating conditions in order to show the robustness of the applied controller in terms of ripple reduction, tracking speed, switching loss, and parameter sensitivity.
