Keywords: Optimal control, adaptive control, underwater vehicle dynamics
Abstract: This article contains a continuous-time optimal and adaptive control scheme for underwater vehicles moving in six degrees of freedom. The control scheme is an extension of the algorithm ofJohansson (1990) and a modification of the algorithm found in Sagatun (1992). The algorithm is optimal in the sense that it minimizes the state errors and the forces which contribute to the vehicle´s kinetic energy that is spent to correct these errors. The performance measure does also contain a term which penalizes the quadratic tracking errors proportional to the rate of energy which dissipates from the system due to damping.
