Original Abstract

This paper presents an effective compensation approach to reduce voltage error which is caused by conversion of the command phase voltages to the output voltages of the inverter. As a result of non-ideal behavior of the switching elements during the switching cycle and overall design of the invertor. The disturbance voltages cause deformation of the phase currents, torque pulsation and overall affect the control algorithm of the PMSM. The disturbance observer is developed to instantaneously estimates the disturbance voltages. It is based on the model of PMSM, known machine parameters and easily measurable variables. The validity of the proposed approach is demonstrated through results of simulations and real experiments.
