Abstract :
This paper presents a comparative study between field oriented control (FOC) and direct torque control (DTC), two most popular control strategies for inverter fed interior permanent magnet synchronous motor (IPMSM) drives. The comparison is done in four switch three phase (FSTP) inverter scheme instead of six switch three phase (SSTP) inverter scheme. The FSTP inverter scheme is better than SSTP inverter scheme because of the reduction in price, switching losses and the complexity of the control board. The comparison is based on various conditions such as normal operating condition, sudden change in load torque, speed reversal and change in stator resistance. To validate the effectiveness of the drive systems, simulation is carried out in MATLAB environment. The simulation results and comparative study have been found quite satisfactory.
