It meets the nano positioning accuracy requirements of piezoelectric staging . 1 Introduction Piezoceramic actuator is widely applied in the field of precision positioning because of its large driving force, and its advantages of high resolution, high frequency response and compact structure, but because inherent hysteresis nonlinearity of these smart materials seriously restricte the control accuracy of the positioning system [1].Therefore, the correct description and elimination influence of the hysteresis nonlinearity becomes the focus of research.
This paper presents an online modeling method based on genetic algorithm to optimize BP neural network, and improves the modeling accuracy of micro displacement staging. 2 Hysteresis nonlinearity of the micro displacement staging Hysteresis of piezoceramic materials is a kind of nonlinear corresponding relation between input voltage and the output displacement, its characteristic curve is as shown in Figure 1[2].
