摘要
证明了一大类含有未知参数的多输入非线性串级系统在适当的假设条件下是可全局适应稳定的。自适应控制律的设计是基于 backstepping递推设计方法 ,得到的参数自适应律的阶次等于未知参数的个数 ,因此该设计是非过参数化的。
An adaptive design procedure is proposed for a broader class of multi input cascade nonlinear systems. The derived adaptive controller guarantees the global boundedness property for all signals and at the same time, steers the states to the origin. The adaptive control design is based on backstepping recursive design technique. The number of parameter estimates is minimal, that is, equal to the number of unknown parameters. The adaptive systems designed by this procedure possess stronger stability than those using overparametrization.
