| Abstract |
An ultra-precise micro/nanopositioning system is one of the key requirements for the rapid advancements in the field of micro/nanotechnology. A frequently used actuator in micro/nanopositioning systems is the piezoelectric actuator, which, although precise, exhibits some unwanted phenomena like hysteresis, creep and high frequency vibrations. Hysteresis is recognized as the main nonlinearity in the piezoelectric actuator and introduces severe control issues for accurate positioning. In this paper, first of all, the mathematical model of the considered micropositioning system is identified from the real-time experimental data. For this purpose, a chirp input signal of varying frequency is applied to the piezoelectric stage to cover the bandwidth of the studied system. To represent the nonlinear hysteretic behavior of the piezoelectric actuator, the Bouc-Wen hysteresis model is considered, and the parameters of this model are identified by using the nonlinear curve fitting problem which is solved in a least-square sense. The hysteresis compensator is then designed, as a feedforward compensator, without finding an inverse hysteresis model to avoid the inverse modeling complexity. To further improve the tracking performance, an intelligent fuzzy feedback controller cascaded in series with the feedforward compensator is proposed and results are compared with the classical PID feedback controller. The achieved results with the proposed control scheme show the improvement in terms of tracking precision and also in compensating the hysteresis nonlinearity as compared to the classical PID feedback controller. |
