Abstract: This paper presents a direct torque and flux control (DTFC) method of PV array fed permanent magnet synchronous machine in (d-q) frame. This method retains the traditional DTFC principle of decoupling torque and flux control to compensate the torque and flux errors in a smooth manner with conventional DTFC, while providing greater use of voltage source inverter using optimal switching. Also a feedback path using PI controller is introduces in this system to regulate the speed and to reduce the error. Here, we have presented satisfied results of DTFC method in PMSM with close loop speed controller. All the results are performed in MATLAB Simulink platform.
