This paper addresses the issue of guidance and control of an autonomous underwater vehicle (AUV) for a cable tracking problem. A linear quadratic Gaussian controller with loop transfer recovery (LQG/LTR) is developed because of its strong robustness properties. The vehicle is guided towards the target using a combination of different guidance algorithms. The vehicle speed is used to formulate the guidance problem. Simulation results are presented and a comparison is made between fix and variable AUV speeds.
