- Abstract:
-
Based on the ship roll problem, the dynamic model equations of an integrated stabilization system were analyzed and proved this to be a chaotic system.The analytical method of phase diagrams and Lyapunov indexes were used to verify the chaotic motion of the system under certain conditions, then a nonlinear feedback control method was used to control this chaotic motion by choosing reasonable control parameters. This method reduced the chaotic motion of the system without destroying the original dynamic characteristics.The chaos search algorithm was combined with an ant colony algorithm to search the best parameters for PID. Therefore, the chaos ant colony optimization algorithm not only had strong global optimization ability but also accelerated the convergence speed. As a result, the performance of the control system was significantly improved.
