本文研究了压电作动器的控制问题。采用受连续时间布温模型启发的离散时间迟滞模型来描述迟滞现象。我们尝试将新模型与自适应控制技术相融合，对模型中的未知参数进行在线更新。该控制算法保证了闭环系统的稳定性。实验结果验证了该方法的有效性。
This paper deals with the control problem of piezoelectric actuators. A discrete-time hysteresis model which is inspired by continuous-time Bouc-Wen model is used to describe the hysteresis phenomenon. We try to fuse the new model with the adaptive control techniques, where the unknown parameters in the model are updated online. The control algorithm ensures the stability of the closed-loop system. Experimental results verify the effectiveness of the proposed method.
