| 摘 要： | 针对一个具有多输入、强耦合、非线性的CE150直升机系统，给出了一种有限时间
控制方案. 该方案首先将整个直升机模型看作一个级联系统，通过坐标变换并采用基于限时间
控制的嵌套饱和方法分别对两个子系统进行有限时间镇定；然后验证前向一致性，保证了整
个闭环系统的全局有限时间镇定. 仿真结果表明，该方案不但有效而且具有更好的收敛性和
鲁棒性.

| Abstract: | A finite-time control method is proposed for the CE150 helicopter with multiple
inputs, strong coupling and nonlinearity. By considering the helicopter system as a cascaded
one and performing coordinate transformation, a finite time nested saturation method is
used to stabilize the two subsystems in finite time. The closed-loop system achieves global
uniform finite-time stabilization by verifying the forward uniformity. Simulation shows
effectiveness of the system, faster convergence, and better robustness. |
