The tracking control accuracy of piezoelectric actuator is limited due to their inherent hysteresis nonlinearity. Based on this reason this thesis aims to the method of improving and compensating the motion of PEA. First this thesis will compare several general PEA models for initial studies. A simple PEA hysteresis model is proposed for practical application. Experimental simulations evinced the developed model is sufficient to describe the hysteresis shape. Secondly, two feed-forward controllers for compensation on the basis of proposed model were designed. One was based on the model reference with tuned delayed time parameter. The other used the model reference as for feedback linearization controlling block in the feedback loop. Two methods for open-loop compensation experiments were conducted via PC-based controller. Experimental results show that the tracking performance is noticeably improved by feedforward compensation when proposed model was implemented. Yi-Cheng Huang 黃 宜 正 2003 學位論文 ; thesis 97 zh-TW |
