Bouc-Wen Hysteresis Model Identification by Improved Jaya Algorithm for Piezoelectric Ceramic Actuator

The Bouc-Wen hysteresis model can simulate the hysteretic nonlinearity of piezoelectric ceramic actuators(PCA) accurately. In order to identify the unknown parameters of the Bouc-Wen model, An improved Jaya algorithm was proposed in this paper. the concept of elite solution and sub-population is added and the variable updating equation is changed in the improved Jaya algorithm. To verify the effectiveness of the proposed improved Jaya algorithm, it has been tested on NiH function and compared with original Jaya algorithm. Finally, Bouc-Wen model identified by improved Jaya algorithm was experimentally verified on a micro-vibration control experimental platform and can converge to steady-state fast with VSS-FXLMS algorithm.
