Control of chaotic behavior in thruster motor system for deepwater ocean robot

Abstract

In this paper, an adaptive control technique is applied to controlling the chaotic behavior in thruster motor system for deepwater ocean robot. This chaotic oscillation has a direct impact on the stability, reliability and security of the robot. In addition, the proposed approach is also verified in the way of both flexibility and effectiveness, and a kind of chaotic controller that is applicable for manufacturing is designed and constructed. The simulation results show that thruster motor system can escape from the chaotic state in a short time by using the adaptive controller and transfer into continuous stable state. The method presented has an obvious effect on the control.
