High performance ships have a lot of advantages, but would cause a larger heeling than normal ships when turning in the high-speed. In this paper, we study the design method of joint controller for the hydrofoil catamaran nonlinear course in three degrees of freedom with heeling using Lyapunov's direct method and fuzzy control method. Firstly, according to the turning characteristics, we give a simplified...
Differential uncertainty is involved in actual system inevitably. That brings great inconvenience for the controller design. In this paper we treat the differential uncertainty as a separate item, and use the robust control theory to analyze the robust performance. Considering the impact of parameter variations, un-model dynamics and external disturbances, we design robust H2/H8 controller. We use...
This paper presents a method for reconstruction of entire three-dimensional objects based on principles of the rotational stereo. The experimental system, which has three degrees of freedom (two for translation and one for rotation), uses an accurate stage to make all areas of the object surface visible. It only needs one camera to capture images and thus reduces the implementation cost. The object...
