| 摘要: |
| 在建立系统全包线T-S模糊模型的基础上,基于系统品质要求和可测状态约束条件,采用参数鲁棒设计方法,确定反馈控制参数的可用集合,实现等效控制律,相应确定系统的滑模面参数,给出了直升机纵向控制系统的全包线滑模控制律设计结果。仿真结果显示,系统具有较强的抗外界干扰能力,动态品质满足指标要求,表明文中提出的设计方法可行且有效。 |

| Abstract: |
| Sections 1 through 4 of the full paper explain our design method mentioned in the title, which we believeis new and more effective than previous ones. Their core consists of: (1) we establish the T-S fuzzy model of a hel-icopter in its whole envelope; (2) we use the parameter robust design method to determine the sets of availablefeedback control parameters; (3) we implement the equivalent control law in accordance with the requirements ofthe performance of the helicopter and the constraints of measurable states; (4) we determine the sliding mode sur-face parameters of the helicopter and design the sliding mode control law for its longitudinal model in the whole en-velope. Section 5 simulates the sliding mode control law thus designed; the simulation results, given in Figs. 8 and9, and their analysis show preliminarily that our sliding mode control law has strong interference-suppression capa-bility and satisfies the dynamic performance requirements for the helicopter, indicating that our design method is in-deed feasible and effective. |
