    摘要:

    为实现电动振动台振动输出力的高精度跟随控制,对交流伺服电机驱动的振动台输出力跟随控制策略进行研究。采用基于输出力、位移和速度的三参量控制器作为控制算法,在Matlab/Simulink平台上运用实数编码遗传算法对三参量前馈控制器参数优化整定,并进行正弦输出力跟随控制仿真;构建以TwinCAT实时控制软件为基础的振动输出力跟随控制实验系统,对四组振动输出力信号进行跟随实验研究。实验结果证明了电动振动测试装置和振动输出力跟随控制策略的有效性和正确性。

    Abstract:

    In order to achieve high-precision vibration output force tracking control of the electric shaking table, the output force tracking control algorithm of the vibration test experiment system driven by alternate current (AC) servo motor is studied. The three parameter controller, which is based on output force, displacement and speed, was used as the control algorithm. On Matlab/Simulink platform, the three parameter feedforward controller parameters were optimized and set with a real-coded genetic algorithm, and the simulation on sinusoidal output force tracking control was conducted. After a vibration output force tracking control experimental system based on the real time control software TwinCAT was built, the tracking experiment researches on four groups of vibration output signals were carried out. Experimental results testify the effectiveness and correctness of the electric vibration test device and the vibration output force following control strategy.
