Tilting capacitive tilt sensor dynamic characteristic analysis

On the basis of analysis on the pendulum capacitive tilt sensor principle and mechanical model, the dynamic charac teristic equation and transfer function is derived. Theoretical analysis shows that the dynamic performance can be significantly im proved by properly chosing sensitive material and the damping medium. The software compensation algorithm also can improve the dynamic performance of the sensor, reduce the dynamic error, so as to improve the effect of sensor measurement. The Matlab simu lation and experimental results confirm the feasibility of the optimization scheme, to meet the actual measurement of sensor＇s dynam ic performance requirements.
