This paper presents a visual servo and fuzzy-PID controller to enable underwater robot station-keeping. Movements of underwater robots are easily disturbed by water flow or external factors in a deep-water environment. In this study, control systems are used to adjust the underwater robot's propeller, which reduces chattering of the robot's postures, and visual target feedback and an accelerometer...
This paper considers the problem of chaos synchronization based on fuzzy sliding mode control and its applications to image encryption. We applied the fuzzy sliding mode controller to achieve chaos synchronization. Then, the Duffing-Holmes chaos states are used to act as the encryption key of cipher text. When their initial values of chaotic states are different, the state sequences are uncorrected...
In this manuscript, we present a novel method to solve Lorenz chaos problem. As we known, the traditional fuzzy logic control method, it spends a lot of time to determine the membership functions and fuzzy if-then rules by trial-and-error tuning. To overcome these drawbacks, we propose to design an interval fuzzy type-2 controller with the sliding surface. The fuzzy if-then rules are defined based...
