Abstract

A high performance load torque observer for impact drop compensation of a motor drive system has been realized by using a digital signal processor (DSP). This observer unit realizes high speed response and low noise characteristics by the DSP's software. The software is constructed with three functions; An improved load torque observer for high speed estimation, a moving average filter for eliminating torque pulsation component caused by inequality in firing angles of converter arms, and a variable filter for reducing noise contained in the estimated load torque. Use of this observer unit with a motor drive system offers high stability and impact drop compensation effect.
