Abstract

In this paper, a new method for controlling electric dynamometer based on fuzzy control is presented. Due to the advantages of squirrel cage induction motors, such as simple structure, good reliability and low maintenance cost, these motors are suitable for use as dynamometer to provide dynamic load for torque-speed or speed-power curve characteristics. In order to obtain better torque control performance and induction motor speed, Direct Torque Control (DTC) method is implemented based on space vector modulation (SVM) technique with fuzzy method. The fuzzy method is used instead of PI or hysteresis Torque and flux comparators. For the dynamometer simulation, a 200-horsepower squirrel cage induction motor is connected to a 200-hp direct current motor via the shaft model. The performance simulations of the proposed dynamometer system were evaluated in three study modes for each of the hysteresis direct torque control, PI torque control and fuzzy direct torque control approaches by Matlab / Simulink software. The simulation results show the significant effect of the fuzzy method on reducing the response speed fluctuation and reducing the torque ripple. The results show that it is possible to use high power motor for electric dynamometer.
