| dc.description.abstract | Piezoelectric material has been widely used as both actuator and sensor in many physical instruments and devices applications, due to its capability and characteristic to react in either way, for example, piezoelectric actuators are used in medical imaging by providing nanometre positioning resolution. However, the undesirable behaviours in piezoelectric material are the nonlinear correlations that subsist in the material to produce the utmost performance. Studies found that some of the nonlinear relations that exist within the piezoelectric actuator are the hysteresis effect, whereby the output displacement of the piezoelectric actuator does not perform an identical reading for each series of measurements. More, the creeping effect also has become an immediate finding whenever most hysteresis loops are measured. Other nonlinear relations such as saturation effect and uncertainty vibration are also found within the piezoelectric actuator. Many approaches have been made to model and also conjugate these nonlinearities effects, especially using different types of mathematical approaches such as the Prandtl-Ishlinski model and Preisach model. These methods are quite complicated rather than using polynomial-based functions where this approach is not only able to model but also inverse the effect of nonlinearity directly. This paper proposed a correction modelling of hysteresis, creep, saturation and uncertainty vibration based on polynomial functions and validate the correction effect through simple a simulation. | |
