Abstract

This paper investigates the recoil control of the deepwater drilling riser system with nonlinear tension force and energy-bounded friction force under the circumstances of limited network resources and unreliable communication. Different from the existing linearization modeling method, a triangle-based polytope modeling method is applied to the nonlinear riser system. Based on the polytope model, to improve resource utilization and accommodate random data loss and communication delay, an asynchronous gain-scheduled control strategy under a hybrid event-triggered scheme is proposed. An asynchronous linear parameter-varying system that blends input delay and impulsive update equation is presented to model the nonlinear networked recoil control system, where the asynchronous deviation bounds of scheduling parameters are calculated. Resorting to the Lyapunov–Krasovskii functional method, some solvable conditions of disturbance attenuation analysis and recoil control design are derived such that the resulting networked system is exponentially mean-square stable with prescribed H performance. The obtained numerical results verified that the proposed nonlinear networked control method can achieve a better recoil response of the riser system with less transmission data compared with the linear control method.

摘要

针对受非线性张紧力和能量有界摩擦力影响的深水钻井隔水系统, 本文研究了其在网络资源有限和不可靠通信情况下的反冲控制问题. 不同于现有的线性化建模方法, 本文将基于三角形的多面体建模方法应用于非线性隔水管系统. 基于该多面体模型, 为提高资源利用率并容许随机数据丢失和通信时延的发生, 提出混合事件触发方案下一种异步增益调度控制策略. 将非线性网络化反冲控制系统建模为带有输入时延和和脉冲更新方程的异步线性参变系统, 并给出调度参数的异步偏差界计算方法. 运用Lyapunov–Krasovskii泛函方法, 提出干扰抑制分析和反冲控制器设计的一些可解条件. 这些条件可以保证最终的网络化系统指数均方稳定且具有指定的H性能. 数值分析结果证实, 在使用较少通信数据的情况下, 相比线性控制, 所提非线性网络化控制能获得更好的反冲响应.
