Abstract

Aiming at shortage of traditional rebalance loop of quartz flexible accelerometer

an accelerometer digital rebalance loop is researched and designed. By system parameter identification method to obtain mathematical model for gauge outfit of accelerometer; using incremental PID control algorithm

design closed-loop system of accelerometer; as for hardware structure

floating-point DSP is chosen as control unit

adopt expanding type AD / DA module to improve conversion precision. Experimental results show that bandwidth of accelerometer system is 190Hz and response time is 1. 6ms respectively

steady-state error is 0. The digital rebalance loop effectively improve static and dynamic performance

significantly improves output precision.
