Abstract

The optical tracking system mainly encounters the problems of sensor delay and external physical disturbance. We propose a method combining Smith predictor and disturbance observer based on Micro-Electro-Mechanical System (MEMS) gyroscope to improve velocity closed-loop bandwidth and disturbance suppression ability. The experimental results demonstrate that the velocity closed-loop bandwidth is increased by about 10 Hz and the disturbance suppression ability is increased by about 11 dB in the low and middle frequency domain.
