Micro-vibration Active Control based on FXAPA algorithm

This paper proposed a filter-x affine projection (FXAPA) algorithm based on affine projection (APA) algorithm, by reusing delayed input signals to improve the convergence speed of the algorithm effectively. Considering the dynamics and drive characteristics of the vibration active control system, hysteresis model was established using Bouc-Wen model. Simulation of the three-degree-of-freedom piezoelectric micro-positioning platform and the simulation verification of the control method were realized. The simulation and experiment results verified that the proposed vibration control algorithm of this paper has good control effect in micro-vibration active control.
