Research on Low-Power Control of Offshore Wind Sail Stabilization Devices Based on Single Pendulum Control Simulation

To tackle persistent operational instability and excessive energy consumption in marine observation platforms under wave-induced disturbances, this paper introduces a novel ultra-low-power stabilization system based on pendulum dynamics. The system employs an innovative mechanical configuration to deliberately decouple the rotation axis from the center of mass, creating controlled dynamic asymmetry. In this behavior, the fixed axis serves as a virtual suspension pivot while the camera payload functions as a concentrated mass block. This configuration generates intrinsic gravitational restoring torque, enabling passive disturbance attenuation. And its passive foundation is synergistically integrated with an actively controlled brushless DC motor system. During platform oscillation, embedded algorithms detect angular motion reversals. In addition, their detection triggers an instantaneous transition from motor drive to regenerative braking mode, and transition facilitates bidirectional electromechanical energy conversion. Experimental validation under simulated marine conditions demonstrates steady-state attitude stability with minimaldeviation under consistent low power consumption during constant wave exposure. Meanwhile, the system effectively handles dynamic wave spectrum transitions requiring real-time swing parameter adjustments. The adjustments involve significant angular displacements with varying temporal dynamics. Accommodation is achieved through autonomous power reallocation, enabling rapid stability recovery within a fraction of an operational cycle. Concurrently, consistently high energy regeneration efficiency is maintained across most of the operational envelope (85-97%). These capabilities substantiate the dual achievement of exceptional disturbance rejection in harsh marine environments and ultra-low power operation. This establishes a technically viable paradigm for next-generation energy-autonomous stabilization platforms.
