| 本文研究了具有全状态非对称约束和不确定干扰的严格反馈非线性系统的自适应渐近跟踪控制问题.为
了约束系统状态,首先,引入了一组预设时间性能函数;其次,构建了一种非对称变换函数,将原系统的状态约束问

后, 应用实例验证了方法的有效性. |
| 英文摘要 |
| In this article, the problem of adaptive asymptotic tracking control is studied for strict-feedback nonlinear sys
tems with full state asymmetric constraints and uncertain disturbances. Firstly, a batch of prescribed time performance func
tions are introduced to restrain system states. Secondly, an asymmetric transformation function is constructed which makes
sure the asymmetric state constraints are not breached, then the state constraints problem is transformed into analysing
the boundary of the new variables. By using the transformation method, the feasibility conditions on virtual controllers
are removed. Subsequently, in order to avoid the inherent “explosion of complexity” problem of backstepping methods, a
f
irst-order filter is introduced. Then an adaptive control strategy is presented on the basis of backstepping technique, which
enables system states do not violate constraint boundary and converge to preset boundaries within a finite-time. Mean
while, the output asymptotically tracks the reference signal. Finally, an applied example demonstrates the effectiveness of
the proposed method. |
