Abstract

In this paper, a second order transfer function of a single-axis PZT nanopositioner stage (P-752.21C) is identified around an operating point. The nonlinearity due to the hysteresis is modeled using look-up tables. The validation of the complete model is achieved experimentally. Two control approaches are developed. The former is a PI controller where the control parameters are tuned using Ziegler-Nichols method. The latter is a fuzzy controller like PI. The simulation results in MATLAB/Simulink are affirmed the potentials of the developed control methodologies.
