摘要

针对电动振动台系统在科学研究和其在仪器可靠性试验中的应用，设计了一种性能良好的电动振动台控制系统。首先介绍电动振动台工作原理，并在此基础上确定电动振动台的简化模型，然后采用PID算法调整控制器参数，使用 Matlab/Signal Constraint工具箱对PID控制器进行优化设计。仿真实验结果表明，设计的电动振动台系统具有良好的动态性能并且具有较小的超调量，满足性能要求，能够较好的模拟所给定的信号。%Aiming at the application of electric vibration table system in scientific research and instruments in reliability test,electric vibration table servo control system with high performance was designed.Firstly,control system of electric vi-bration table based on working principle was modeled.Secondly,the conventional PID algorithm was adopted to design the controller .And then a method of using Matlab/Signal toolbox was presented to optimize the controller.The simulation test results indicate that the designed system can meet the requirements with fine dynamic performance and small overshoot and can simulate the signal given.
