Observer-Based Adaptive Fuzzy Control of Time-Delay Chaotic Systems
نویسنده
چکیده
This work presents an observer-based adaptive control approach for time-delay chaotic systems with uncertainty. The chaotic system is initially expressed with the Takagi-Sugeno (T-S) fuzzy model. The design of the adaptive fuzzy observer is introduced based on the assumptions of chaotic system properties. Next, the design principle is applied to stabilization and tracking problems. Based on Lyapunov's stability analysis, the sufficient conditions for synthesizing a stable observer and controller are expressed in the form of adaptive updating laws and linear matrix inequality (LMI). Computer simulation verifies the system, controlled by the proposed method, performs well.

Stabilization of chaotic systems via fuzzy time-delayed controller approac
In this paper, we investigate the stabilization of unstable periodic orbits of continuous time chaotic systems usingfuzzy time-delayed controllers. For this aim, we present a control method that can achieve stabilization of an unstableperiodic orbit (UPO) without any knowledge of the system model. Our proposal is attained progressively. First, wecombine the input-to-state linearizing controller...

In this paper, a fractional-order robust adaptive intelligent controller (FRAIC) is designed for a class of chaotic fractional order systems with uncertainty, external disturbances and unknown time-varying input time delay. The time delay is considered both constant and time varying. Due to changes in the equilibrium point, adaptive control is used to update the system's momentary information a...
