Abstract:

In recent years the industrial application areas of the high performance AC drives based on Direct Torque Controller (DTC) technique have gradually increased due to its advantages over the field oriented control technique. Direct torque control (DTC) is one of the most excellent control strategies of torque control in PMSM. It is considered as an alternative to the field oriented control (FOC) or vector control technique. These two control strategies are different on the operation principle but their objectives are the same. They aim to control effectively the torque and flux. Torque control of an PMSM based on DTC strategy has been developed and a comprehensive study is presented in this research. The performance of this control method has been demonstrated by simulations performed using a versatile simulation package, Matlab/Simulink. Several numerical simulations have been carried out in a steady state and transient operation on a speed control mode. Implementation of an actual drive system based on the suggested DTC including software and hardware, to validate its performance practically is presented. The suggested control strategy guarantees very good dynamic and steady state characteristics. The practical and simulation results show that the used DTC gives good dynamic performance and good tracking response.
