Abstract :
It is necessary to carry out the dynamic compensation for the sensor when its dynamic response speed is slow. Sometimes the effectiveness of dynamic compensation is not good because the dynamic characteristic of sensor is nonlinear. In order to resolve this problem, the dynamic nonlinearity compensation is studied in this paper. The dynamic nonlinearity compensating devices are designed using the FLANN, both the impulse and step responses of robot wrist force sensor are compensated, and good results are obtained. The dynamic nonlinearity compensation results are also compared with that of dynamic linearity compensation, which shows the dynamic nonlinearity compensation is effective
