Robust control of an underwater vehicle

An H-infmity controller has been designed for the heading control of an underwater vehicle. The performance weighting function, and the robustness weighting function, ^^3(^9) were obtained 60m experimental data. The results of simulated heading responses were determined using an underwater vehicle simulation program, y4z/^o7(0)^and MATLAB robust control toolbox. A nonlinear simulation program was also used to observe the behaviour of the underwater vehicle to nonlinear underwater dynamics. The simulated results of the H-infinity controller were compared with the PID controller and results showed that the H-infinity based controller can withstand uncertainties such as random noise and rudder delay better than a PID based controller.

Abstract

An H-infmity controller has been designed for the heading control of an underwater vehicle. The performance weighting function, and the robustness weighting function, ^^3(^9) were obtained 60m experimental data. The results of simulated heading responses were determined using an underwater vehicle simulation program, y4z/^o7(0)^and MATLAB robust control toolbox. A nonlinear simulation program was also used to observe the behaviour of the underwater vehicle to nonlinear underwater dynamics. The simulated results of the H-infinity controller were compared with the PID controller and results showed that the H-infinity based controller can withstand uncertainties such as random noise and rudder delay better than a PID based controller.
