Abstract

The modeling of permanent magnet synchronous motor field-oriented control is used for the operationof the drive. The simulation includes all realistic components of the system. This enables the calculationof currents and voltages in different parts of the inverter and motor under transient and steadyconditions. The losses in different parts are calculated, facilitating the design of the inverter. Closedloop control system with a proportional integral (PI) controller in the speed loop has been designed tooperate in constant torque and flux-weakening regions. Implementation has been done in Simulink. Acomparative study of hysteresis and pulse width modulation (PWM) control schemes associated withcurrent controllers is made in terms of harmonic spectrum and total harmonic distortion. Simulationresults are given for two speeds of operation, one below rated and another above rated speed.
