摘　　要：为了在压电陶瓷执行器微动控制中获得高精度的同时,实现高响应速度,采用三阶轨迹规划方法设计控制算法。为了对控制算法的性能做出准确评价,采用xPC Target实时内核技术,以高速模拟信号采集卡作为控制/反馈信号的I/O通道,搭建了半实物仿真平台,获得了毫秒量级的伺服周期。实验表明,当伺服周期为1 ms、定位行程为200μm时,三阶轨迹规划算法使压电陶瓷执行器可以在0.5 s内完成精度为±1μm的定位,实现了兼顾高精度与高速度的微动控制。该半实物仿真系统可以有效验证控制算法的性能,为算法的后续移植提供了有益参考。In order to obtain a fast response and high-precision in the jogging control of piezoceramic actuator, the control algorithm is designed on third order trajectory planning. For purpose of evaluating the performance of control algorithm accurately, the xPC Target real-time kernel technology is used, with high speed analog signal acquisition card as the I/O channel of control or feedback signal, to set up a semi-physical simulation platform, and achieves a servo period of milliseconds. Experiments show that third order trajectory planning could make piezoelectric actuator locate with an error of ±1 μm in 0.5 s, the jogging control with high accuracy and high speed is realized, when the servo cycle is 1 ms and the position stroke is 200 μm. The semiphysical simulation system could effectively verify the property of the control algorithm, and provide a useful reference for the further application of the algorithm.
