摘要 对三级阀控液压振动台的控制策略进行了系统的研究,设计了应用于大流量液压振动台的一体式控制器。一体式控制器同时实现液压振动台伺服控制及振动控制功能,伺服控制中,针对三级电液伺服阀和伺服油缸提出一种双PID伺服控制策略,振动控制中,针对液压振动台良好的低频特性设计了基于闭环迭代控制的波形再现控制方法。通过一体式控制器对三级阀控液压振动台进行不同时程、不同频宽的波形再现试验,表明控制器对液压振动台具有很好的波形控制能力,实现液压振动台高精度波形再现。 The control strategy for a hydraulic shaker controlled with a 3-stage electro-hydraulic servo valve was studied here.An integrated controller was designed for a large-flow hydraulic shaker.The controller could simultaneously realize servo control and vibration control functions of the hydraulic shaker.In the process of the servo control,a dual-PID servo-control strategy was presented for the 3-stage electro-hydraulic servo valve and the servo cylinder.In the process of the vibration control,aiming at the good low-frequency characteristics of the hydraulic shaker,a waveform replication method based on a closed-loop iterative control was designed.Through the waveform replication tests with different time histories and different bandwidths on the hydraulic shaker controlled with the integrated controller,it indicated that the controller has a strong waveform control ability to achieve a high-precision waveform replication on the hydraulic shaker.
