| Abstract: | The forces on fin stabilizer are analyzed in non-steady flow based on the special working of zero speed fin stabilizer.The lift on zero-speed fin stabilizer is simulated with Fluent software.The lift model is set up and modified with the data from simulation.For the non-linear lift model and uncertainty of the system,PID NN method is used to design the controller for the anti-roll system.Simulation result shows that this anti-roll system has a good exhibition. |
