Application of geometry based hysteresis modelling in compensation of hysteresis of piezo bender actuator
The geometrical description of hysteresis deformation is presented. A new, based on this description, simulation model of piezo element with hysteresis is proposed and implemented in MatlabSimulink software. The model is used for the simulation of non-saturated hysteresis of the piezo bender actuator. The paper presents chosen simulation results, which are compared with results obtained in experimental investigations. The proposed model was inverted and used for the hysteresis compensation. Chosen piezo bender actuator hysteresis compensation results are presented.
