PSO-PID control strategy for ship anti roll slider device under the influence of long peak wave seas

Abstract

Abstract The ship will produce various swaying motions after being affected by wind, waves and other disturbing factors when sailing. among which the transverse swaying motion is the most violent. By the effective control of transverse swaying motion it can improve the safety of ship sailing and the comfort of crew. Thus, in the present study, ship anti roll slider device is chosen as the research subject, and a theoretical analysis on the principle of rocking reduction of ship anti roll slider device is performed. For the problem that the PID controller parameters do not have self-tuning capability, the PID controller parameters are optimized by introducing the PSO algorithm, and the PSO-PID controller is designed on this basis. The PID controller and PSO-PID controller are used to simulate the ship anti roll slider device on Matlab. and the simulation results show that the PSO-PID controller has good rocking reduction effect under different sea conditions, which verifies the effectiveness and superiority of the PSO-PID controller.
