On impulsive parametric perturbation control techniques for chaotic ship steering

Ship is maneuvering in a complex environment, studies showed that chaotic state appeared when ship steering. This movement easily leads ship out of control or off course, and also affects the special deck operations and even endangers the ship´s own security. In order to achieve the purpose of controlling chaotic ship steering, a method based on improved double-pulse parameter perturbation is presented and the control results are showed. After that, a periodic rectangular impulsive parameter perturbation control method based on Melnikov´s method for chaotic ship steering control is proposed. The experiments results show that the proposed method overcomes the shortage of trial method and can fix the control parameters value range in mathematics way by structures the controlled system´s Melnikov function, and the control effectiveness is demonstrated.
