| 英文摘要 |
| We propose a method for designing the adaptive fuzzy backstepping controller for a nonlinear system with
input saturation. In this method, we use the fuzzy logic system to identify the uncertain nonlinear functions online, and
employ the hyperbolic tangent function and Nussbaum function to handle the input saturation. By combining the backstepping
recursive design with dynamic surface control (DSC) technique, we solve the problem of “computation explosion”.
By using Lyapunov theory, we prove that this controller ensures all signals in the closed-loop system to be semi-globally
uniformly ultimately bounded (SGUUB) in probability. This method has been applied to the design of the attack angle of a
hypersonic vehicle. Simulation results are given to show the effectiveness of the proposed method. |
