英文摘要 | This paper presents an indirect adaptive control scheme for a class of input-output linearizable nonlinear systems subjected to system perturbations. System parameters are unknown and estimated recursively by a parameter estimator to obtain approximate system output and output derivatives, and then to derive an adaptive control law. In the parameter estimator, a dead-zone approach is used to avoid the parameter drift problem. A positive switching gain is also set to decrease the dead-zone value to obtain better output tracking performance. Under some assumptions, the indirect adaptive control scheme is proved to be stable. |
