Abstract

Li, F., 2019. Offshore platform actuator fault optimal anti-interference self-repair fault-tolerant control. In: Gong, D.; Zhu, H., and Liu, R. (eds.), Selected Topics in Coastal Research: Engineering, Industry, Economy, and Sustainable Development. Journal of Coastal Research, Special Issue No. 94, pp. 153–156. Coconut Creek (Florida), ISSN 0749-0208.

A fault-tolerant control method based on extended fault diagnostics is proposed for the actuator failure of offshore platforms under the influence of ocean waves. Firstly, a self-repairing fault-tolerant control law is designed for actuator failure. Then an optimal anti-interference self-repairing fault-tolerant controller is designed according to Riccati and Sylvester matrix equations to ensure that the offshore platform system is optimal under fault and wave interference. In order to solve the physical unrealizable problem that the system state and faults in fault-tolerant control cannot be directly measured, an extended fault diagnostic device is designed. Finally, numerical simulation results verify the feasibility and effectiveness of this scheme.
