基于LabVIEW FPGA的压电陶瓷驱动器位移控制研究
|
摘要
针对传统实时模块存在的响应速度较慢、采样周期较长等缺点,不能满足压电陶瓷驱动器快速响应的要求,在LabVIEW FPGA模块下搭建了压电陶瓷驱动器的控制系统,并采用PID控制方法进行压电陶瓷驱动器的位移控制实验研究。实验结果表明:与实时模块PID控制方法相比,基于LabVIEW FPGA模块PID控制方法能有效提高压电陶瓷驱动器的动态性能,响应时间由37 ms降低到15 ms,且基本无超调。
The disadvantages of slow response speed and long sample period exist in the traditional real time module,so it cannot meet the requirements of fast response of piezoelectric actuator. A control system of the piezoelectric actuator is built under the LabVIEW FPGA module and PID control method is used to control the piezoelectric actuator. The experimental results show that PID control based on the LabVIEW FPGA module can be used to improve the dynamic performance of the piezoelectric actuator,the step response time is reduced from 37 ms to 15 ms and basically no overshoot exists,compared with normal PID control.
