Then, the problem of manoeuvrability control for this vehicle is formulated as an unconstrained optimal control problem which is solved by using a gradient descent method. Simulation results presented are rooted by two requirements which are of a major importance in naval industry, and they are compared to a classical linear model. %K Matemática Aplicada %K Control de maniobrabilidad %K Submarino %K Control óptimo %K Método de descenso rasante %K Manoeuvrability control %K Submarine %K Optimal control %K Gradient descent method %~ GOEDOC, SUB GOETTINGEN
