Decoupling Strategy of Multi-dimensional Force Sensor Based on LS-SVM and Dth-order Inverse System Method

摘要：

The coupling of multi-component force sensor is a key factor to limiting its measuring precision. It has become a popular direction of study. The αth-order inverse system decoupling strategy is newly proposed in the paper. One strong coupling MIMO system is decoupled into a number of 2nd-order integral subsystems. The dynamic calibration experiments should be processed by applying loads on the force sensor. In this way, the dynamic character of force sensor would be caught. The dynamic relations among inverse system could be indicated with integrators. Static nonlinear functions approximation of correspondence of inverse system is implemented via training learning network of LS-SVM. Finally, the decoupling of force sensor was realized. Simulation examples verified the availability of the method.
