Paper Abstract

A major limitation of piezoceramic actuators is their lack of accuracy due to hysteresis nonlinlinearity. The modified preisach model was used to describe the hysteresis of piezoelectric actuator. The output prediction using this model was compared with experimental data. A comparison was made between a regular PID feedback control scheme and a PID feedback control scheme with the modified preisach model in the feed-forward loop. The result shows that using this model can reduce the hysteresis of the displacement to voltage from 18.3% to 3.9%, and the maximal relative error between the output prediction and experimental data is 4.1% over the entire working range 0-19 μm. The dynamic response speed and the tracking control accuracy of the piezoceramic actuator are greatly improved by augmenting a feedback loop with the modified preisach model of hysteresis nonlinearity in the feed forward loop.
