提出了一种基于幅值相位控制器和零相位误差跟踪控制器与离散前馈补偿器相结合的电液振动台加速度控制新策略。由于电液系统的非线性，电液振动台系统在正弦振动信号激励下，加速度响应信号不可避免地存在相位滞后和幅值衰减。电液振动台的相位延迟由相位偏差和作动器延迟两部分组成。为了提高加速度跟踪精度，采用幅相控制器，通过引入权值调整参考信号，补偿相位偏差和幅值衰减。同时，离散前馈补偿器被用来补偿执行器的延迟。作为离线补偿器，零相位误差跟踪控制器被用来补偿响应信号的相位延迟，并提高所提出的控制器的收敛速度。总体而言，所提出的控制策略结合了这三种控制器的优点，具有更好的跟踪性能，仿真和实验结果表明。
This article presents a novel control strategy on an electro-hydraulic shaking table under the acceleration control combining an amplitude phase controller and a zero phase error tracking controller with a discrete feed-forward compensator. Because of the electro-hydraulic system’s nonlinearity, phase delay and amplitude attenuation exist in the acceleration response signal inevitably when the electro-hydraulic shaking table system is excited by a sine vibration signal. Moreover, the phase delay of the electro-hydraulic shaking table is composed of phase deviation and actuator delay. For improving the acceleration tracking accuracy, an amplitude phase controller is employed to compensate the phase deviation and amplitude attenuation by introducing weights to adjust the reference signal. Meanwhile, the discrete feed-forward compensator is applied to compensate the actuator delay. As an offline compensator, the zero phase error tracking controller is employed to compensate the phase delay of the response signal and improve the convergence speed of the proposed controller. Overall, the proposed control strategy combines the merits of these three controllers with better tracking performance demonstrated by simulation and experimental results.
