Abstract

Disclosed is a variable parameter comprehensive stabilizing controller based on energy optimization. The variable parameter comprehensive stabilizing controller based on the energy optimization not only is low in energy consumption, but also can achieve good shake reduction ability. The variable parameter comprehensive stabilizing controller based on the energy optimization includes: firstly, analyzing a ship and shake reduction fin system mathematical model and a ship-passive shake reduction water cabin system mathematical model to build a stabilizing fin-passive stabilizing water cabin comprehensive stabilizing system mathematical model; secondly, analyzing interaction of a stabilizing fin and a passive stabilizing water cabin; furthermore, building a secondary performance index, using a genetic algorithm to optimize parameters, and designing a variable parameter PID (proportion integration differentiation) controller based on the energy optimization; finally, simulating concrete experiment ship control, and comparing the concrete experiment ship control with traditional PID control.

Description

technical field [0001] The invention relates to a ship anti-rolling controller, in particular to a variable-parameter comprehensive anti-rolling controller. Background technique [0002] Ships sailing at sea are disturbed by sea wind, waves, and currents, which will produce motions in six degrees of freedom, including roll, bow, and heave, among which roll motion is the most violent. Severe rolling motion will make the equipment on the ship not work normally, the deck will be flooded, and the crew will feel uncomfortable in work and life; for warships, it will affect the aiming of the artillery system, reduce the efficiency of soldiers on duty, and make the carrier aircraft unable to take off and land safely. In order to effectively reduce ship rolling, various anti-rolling devices have been invented, among which fin stabilizers, passive anti-roll tanks, anti-roll rudders, and bilge keels are more commonly used after considering cost and reliability. When designing, it shou...
