Paper Abstract

The tracking servo system of an optoelectronic tracking system that is driven by unipolar PWM power amplifier has the features of high efficiency, wide speed regulation range. But the phenomena such as instability at low-speed and positioning exist in the system because of dead-zone nonlinearity, which result in steady error and low tracking precision. A method for improving low-speed performance of an optoelectronic Tracking System is given in the paper: using bipolar PWM power amplifier to replace unipolar PWM power amplifier and we did some comparative experiments. The experimental results showed that using bipolar PWM power amplifier to replace unipolar PWM power amplifier is an effective method for improving the low-speed performance of the optoelectronic tracking system.
