| 中文摘要 |
| 本文研究了一类不确定严格反馈非线性系统的预定性能控制问题. 为保证系统预定性能, 引入了一个简单的障碍型Lyapunov函数. 结合反推设计法, 给出了一种新的自适应控制算法. 理论与实验结果表明, 所得控制器不仅保证了系统预定性能, 且使得闭环系统所有信号有界. |
| 英文摘要 |
| The prescribed performance control problem is investigated for a class of uncertain nonlinear systems in strict-feedback form. To ensure the prescribed performance, a simple barrier-type Lyapunov function is introduced. By following the backstepping approach, we develop a novel adaptive control algorithm. It is shown both analytically and numerically that the proposed control scheme is effective in ensuring the prescribed performance and maintaining the boundedness of all signals in the closed-loop system. |
