To improve the dynamic characteristic of two-axis force sensors, a dynamic compensation method is proposed. The two-axis force\r\nsensor system is assumed to be a first-order system. The operation frequency of the system is expanded by a digital filter with\r\nbackward difference network. To filter high-frequency noises, a low-pass filter is added after the dynamic compensation network. To\r\navoid overcompensation, parameters of the proposed dynamic compensation method are defined by trial and error. Step response\r\nmethods are utilized in dynamic calibration experiments. Compared to experiment data without compensation, the response time\r\nof the dynamic compensated data is reduced by 30%~40%. Experiments results demonstrate the effectiveness of our method.
