Abstract:

Path Planning is an intricate part of the navigation function of any vehicle traveling between two points in space. In an autonomous underwater vehicle, a trajectory may be planned between two points using the optimization techniques of ADS Advanced Design Synthesis coupled to a motion analysis routine, DSL Dynamic Simulation Language. The problem is posed as a two-point-boundary-value problem with initial states and desired final states known, as well as a final time specified. The objective function is minimized in the form of a quadratic regulator for the purpose of conserving the vehicles energy supply. An obstacle in the dive plane X-Z plane is introduced and successfully avoided using the constrained optimization technique. The use of optimization is proven as a feasible method for successfully planning the trajectories of underwater vehicles.
