Abstract

This paper proposed the direct torque control method for current source inverter fed PMSM to achieve high performance at low speed operation. During low speed operation estimation of stator flux and torque for direct torque control is very difficult due to the variation in stator resistance. This parameter variation from the set value affects the system at low speed of the PMSM. Many controlling techniques were introduced to compensate the stator resistance variation. A novel Fuzzy Logic Control method is used to compensate the stator resistance variation and the simulation results and hardware results are prove that the performance of the CSI fed PMSM has been improved.
