A Correcting Method of Frequency Domain for Sensor's Dynamic Error

Xu Kejun; Li Cheng (Hefei University of Technology,Hefei 230009)  
This paper improves greatly the correcting method of frequency domain for sensor's dynamic error,and enlarges its scope of application. A more reasonable correcting transfer function is adopted,the correcting precision is raised. The real time correcting link is set up by using the complex curve fitting method,and the correction is implemented on line. The correcting results of dynamic signal for robot's wrist force sensor prove this method to be efficient and applied.
