摘　　要：压电陶瓷的迟滞、非线性和蠕变特性,降低了它的定位精度,且给压电陶瓷微定位系统的控制带来困难。该文提出一种新的智能逻辑规则控制算法,仿真结果表明,与PID控制算法相比,控制器输出不仅超调量小、响应时间快,而且控制器的控制精度可以预先设定并通过直接调节参数而满足,满足了压电陶瓷微定位系统高精度的要求。The hysterics,non-linearity and creep characteristic of piezoelectric ceramic depress its positioning accuracy, and give some difficulties to control for piezoelectric ceramic micro-positioning systems.In this paper, a new intelligent logical rule control algorithm is presented.Its simulation results prove that compared with PID control algorithm, not only output of controller is small overshoot and rapid respond time,but also control accuracy of controller can be given at first and solved by direct adjust parameters. It fits for higher accuracy of piezoelectric micro-positioning systems.
