Zero-speed fin stabilizer is applied to reduce the roll motion of ships at zero speed. This paper aims to explore the control strategy of zero-speed fin stabilizer through a composite method of theoretical analysis, simulations and tank tests. The hydrodynamic force model is established using analytical approach and a simplified model is obtained by fitting the CFD simulation data. The control strategy of zero-speed fin stabilizer is obtained based on disturbance and compensation by analyzing the phase matching relationship between the wave disturbance, the roll motion of the ship, the movement of the fin and the fin-induced hydrodynamic force. Simulations and water tank tests are performed to verify the effectiveness and feasibility of the obtained control strategies. The results of simulations and tank tests show that the obtained control strategies of zero-speed fin stabilizer based on disturbance and compensation are effective and practical. The proposed method provides theoretical and experimental support for engineering application, and can also be a reference for the controller design of zero-speed fin stabilizers.

“…Then, the singular perturbation approach was introduced in [2] to analyze the marine vehicles rudder roll stabilization problem. The chart for roll stabilization of a marine vehicle is presented in [5], see Figure 2. Notice that [5] was focused on the methodology by which we arrive at the amount of stabilising moment to apply at any roll angle when a marine vehicle is sailing in waves.…”

“…Energy consumption caused by overcoming the resistance and the yaw was analyzed in [4], and the self-tuning PID controller based on the MOGA method is used to optimize the performance index which has the added resistance consumption. Relevant research work based on roll additional resistance is proposed in [5]. Energy consumption used for driving fin stabilizer is added to performance in [6], GPC controller is designed, and recursive least square method is adopted for parameter estimation.…”

This paper presents the design and simulation validation of a multivariable GPC (generalized predictive control) for AUV (autonomous underwater vehicle) in vertical plane. This control approach has been designed in the case of AUV navigating with low speed near water surface, in order to restrain wave disturbance effectively and improve pitch and heave motion stability. The proposed controller guarantees compliance with rudder manipulation, AUV output constraints, and driving energy consumption. Performance index based on pitch stabilizing performance, energy consumption, and system constraints is used to derive the control action applied for each time step. In order to deal with constrained optimization problems, a Hildreth’s QP procedure is adopted. Simulation results of AUV longitudinal control show better stabilizing performance and minimized energy consumption improved by multivariable GPC.
