电动液压振动台（EHST）用于实时复制土木和建筑工程、汽车工业和抗震测试中发生的情况。EHST能够在很宽的频率范围内以高速产生很大的力，这一特性使它们在进行振动测试时非常有用。不幸的是，由于EHST系统的液压系统的固有动力学，EHST系统的输出响应响应显示响应于位移和加速度命令的幅度衰减和相位延迟。提出了一种前馈逆模型（FANTS）与自适应逆控制（AIC）相结合的方法，以提高EHST对给定位移和加速度指令的跟踪性能。提出的控制策略利用一个FANGLE扩展EHST系统的频率带宽，并使用AIC基于递归最小二乘（RLS）算法的自适应调整EHST伺服控制器的时域驱动信号，提高跟踪精度。实验和仿真结果验证了所提出的组合控制策略的有效性。
An electro-hydraulic shaking table (EHST) is used for real-time replication of situations that occur in civil and architectural engineering, the automotive industry, and earthquake resistance testing. EHSTs are able to generate a large force at high speeds over a wide frequency range and this feature makes them invaluable in performing vibration tests. Unfortunately, due to the inherent dynamics of the EHST system’s hydraulics, the output response of an EHST system displays magnitude attenuation and phase delays in response to displacement and acceleration commands. A feedforward inverse model (FFIM) combined with adaptive inverse control (AIC) is proposed to improve the tracking performance of the EHST following specified displacement and acceleration commands. The proposed control strategy utilizes a FFIM to extend the EHST system’s frequency bandwidth and uses AIC based on a recursive least squares (RLS) algorithm to adaptively adjust the time domain drive signal of the EHST servo controller and improve the tracking accuracy. Experimental and simulation results demonstrate the effectiveness of the proposed combined control strategy.
