摘要:

本文提出了一种新的自适应控制方法,用于解决不确定纯反馈非线性系统在可转换为伪仿射形式下的全局渐近状态稳定问题。考虑的伪仿射纯反馈非线性系统具有非线性参数化不确定性和可能的未知控制系数。基于参数分离技术,采用自适应高增益思想设计回步控制器。严格稳定性分析显示,所提出的控制器能保证对于任何初始系统状态,闭环信号有界性和状态的全局渐近稳定。通过数值和现实例子验证了所提控制方法的有效性。

英文摘要:

A novel adaptive control approach is proposed to solve the globally asymptotic state stabilization problem for uncertain pure-feedback nonlinear systems which can be transformed into the pseudo-affine form. The pseudo-affine pure-feedback nonlinear system under consideration is with non-linearly parameterised uncertainties and possibly unknown control coefficients. Based on the parameter separation technique, a backstepping controller is designed by adopting the adaptive high gain idea. The rigorous stability analysis shows that the proposed controller could guarantee, for any initial system condition, boundedness of the closed-loop signals and globally asymptotic stabilization of the state. A numerical and a realistic examples are employed to demonstrate the effectiveness of the proposed control method.
