For the defects of conventional direct torque control (DTC) system of switched reluctance motors (SRM), RBF neural network (RBFNN) and fuzzy adaptive PID controller are applied to direct torque control system of SRM in the paper. Switching state table is replaced by RBFNN; fuzzy adaptive PID controller is applied to the outer loop for speed adjustment. In order to verify the validity of the method,...
Fuzzy-PID control is used in the Variable rate fertilization controlling system and the rule of the fuzzy control is determined. Based on the dynamic model of the Variable rate fertilization controlling system, MATLAB/Simulink is applied to simulate the torque and the rotation speed of the engine. The experimental results indicate that the proposed method is of simple arithmetic and real-time characteristics...
Based on fuzzy control strategy, direct torque control (DTC) system of induction motor is designed by making use of a fuzzy controller to choose voltage-space-vectors. Simulation model of this system is realized via Matlab software. Finally, simulation results show that this system has improved dynamic and static performance that the response of torque gets quicker, and the fluctuation of torque turns...
