This paper investigates the hybrid-driven-based networked control for an offshore steel jacket platform subject to external wave forces. A hybrid driven strategy is introduced to deal with the problem of networked control for offshore platforms. Then, the networked closed-loop system is modeled as a stochastic delay system. Based on this model, a stability criterion is derived using the stochastic control theory and the Lyapunov-Krasovskii functional method. Simulation results show that the hybrid-driven-based networked H ∞ controller is effective to suppress the vibration of the platform and save the limited network resources as well. Moreover, the designed controller is flexible in terms of maintaining a balance between performance requirements of the offshore platform and the utilization of communication network bandwidth. INDEX TERMS Offshore platform, networked control system, H ∞ control, stochastic system, hybrid driven strategy.
