Composite Hierarchical Anti-disturbance Control for A Class of Nonlinear Systems with Multi-source Disturbance

摘要：

Anti-disturbance control and estimation problem is introduced for a class of nonlinear system subject to multi-source disturbances. The disturbances classi.ed model is proposed for multi-source disturbances based on the error and noise analysis. The adaptive disturbance observers are constructed separately from the controller design to estimate the disturbance with partial known information. By integrating DOBC with robust adaptive fuzzy control, a novel type of composite hierarchical anti-disturbance control scheme abbreviated as DOBPRAFC is presented for a class of nonlinear system with unknown nonlinear dynamics. Simulations for a .ight control system are given to demonstrate the effectiveness of the results compared with the previous schemes.
