OPTIMIZED FUZZY CONTROL DESIGN OF AN AUTONOMOUS UNDERWATER VEHICLE
In this study, the roll, yaw and depth fuzzy control of an Au- tonomous Underwater Vehicle (AUV) are addressed. Yaw and roll angles are regulated only using their errors and rates, but due to the complexity of depth dynamic channel, additional pitch rate quantity is used to improve the depth loop performance. The discussed AUV has four aps at the rear of the vehicle as actuators. Two rule bases...
متن کاملNonlinear Robust Tracking Control of an Underwater Vehicle-Manipulator System
This paper develops an improved robust multi-surface sliding mode controller for a complicated five degrees of freedom Underwater Vehicle-Manipulator System with floating base. The proposed method combines the robust controller with some corrective terms to decrease the tracking error in transient and steady state. This approach improves the performance of the nonlinear dynamic control scheme a...
متن کاملAn Improved Microscope Lamp.
The new inclined binocular microscopes when used with high-power objectives require much light to illuminate adequately the field of view. At least three times the light is necessary as for a similar optical combination on a monocular instrument. The ordinary opal bulbs even when over-run do not provide sufficient illumination, and of course with them there is no possibility of employing a ligh...
متن کاملAn Image Curvature Microscope
This paper presents a review, analysis and comparison of numerical methods implementing the curvature motion and the affine curvature motion for 2D images, shapes, and curves. These curvature scale spaces allow, in principle, to compute an accurate multiscale curvature in digital images. The fastest and most invariant of them can be used in a complete image processing chain. This numerical chai...
متن کاملAn Approach for Operation Depth Reduction of an Underwater Glider Propelled by Ocean Thermal Energy
The underwater Gliders are a kind of autonomous vehicles that have a special role in ocean surveys which demand continuous monitoring and long endurance. Because of low energy consumption and long endurance, these vehicles are favorite for these missions. Among this, a type of gliders can harvest ocean thermal energy, causing significant endurance increase. These vehicles need at least 680 mete...
