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,...
This paper presents a novel control scheme for a two-phase synchronous reluctance motor (TPSynRM) . A three-leg two-phase inverter is used to drive the TPSynRM. The torque of the TPSynRM is controlled with a direct torque control (DTC) method. DTC uses the space vectors of the three-leg inverter. The speed controller has a two-degree of freedom (TDOF) structure. A pole-zero cancellation (PZC) method...
Vector control based on rotor field orientation control (FOC) and direct torque control based on stator field observation (DTC) are nowadays two mainstream control strategies in modern asynchronous motor speed regulating system. Based on the smooth switching control that is combined with the two control methods in the light of the complementarity each other, the online adaptive parameters estimation...
To solve the problems of torque ripple and inconstant switch frequency of inverter in the conventional direct torque control (DTC) for permanent magnet synchronous motor (PMSM) drive, a novel DTC method using space vector pulse width modulation (SVM) is proposed based on analysis of PMSM mathematical model. In this novel DTC system of PMSM , traditional torque hysteresis controller and flux hysteresis...
The combination of matrix converter with direct torque control is a way towards green energy-saving of the world. It has great sense for theory research and good developing future. First, it is analyzed about working principle of matrix converter, the control principle and its realization process of direct torque control for induction machine inverter-based. Then the comprehensive switching control...
