摘要
目的:研究基于事件触发的海洋平台H_∞模糊主动减振控制方法。方法:采用积分不等式方法和事件触发方法研究海洋平台系统的镇定控制。结果:针对具有主动质量阻尼器装置的导管架海洋平台,提出了一种基于事件触发的H_∞模糊控制器设计方法,给出了海洋平台闭环系统渐近稳定的一个充分条件。最后,进行了数值仿真验证。结论:仿真实例表明,提出的控制方法能有效减少平台在波浪力作用下的振动幅值,提高系统的安全性并且能节约网络资源。
Aims: This paper aims to study on an event-triggered fuzzy H_∞ control method for offshore platforms. Methods: The stabilization control of the offshore platform was studied by using the integral inequality method and the event-triggered approach. Results: For the jacket offshore platform with active mass damper devices, an event-triggered fuzzy H_∞ controller design method was proposed;and a sufficient condition for the asymptotic stability of the closed-loop system of the offshore platform was given. Finally, numerical simulation verification was performed. Conclusions: Simulation results show that the designed fuzzy H_∞ control method is effective to attenuate the vibration of the offshore platform significantly, improves the safety of the offshore platform and saves the network resources.
