中文摘要 |
针对带有交叉耦合的多输入CE150直升机模型, 研究了一类多输入仿射非线性系统的控制设计问题, 基于滑模变结构控制理论, 采用了一种新的控制器设计方法: 滑模降阶方法, 即反复运用变结构控制理论, 对一类高阶的仿射非线性系统, 构造了合适的微分同胚变换函数, 把初始高阶系统降至低阶系统, 并构造了变结构控制律, 再利用当前级和上一级控制输入的映射关系反推出初始系统的控制输入. 通过CE150直升机模型仿真结果表明, 该方法有效可行. |
英文摘要 |
We investigate the design of a multiple-input affine nonlinear system for the multiple-input CE150 helicopter model with cross coupling. A new method for designing the sliding-mode reduced-order controller is developed based on the sliding-mode control theory. For a type of higher order affine nonlinear system, we build appropriate diffeomorphism transformation functions to reduce the initial higher order system to a lower order system by repeatedly using variable structure control theory as well as building variable structure control rule. The control input to the initial system is backward deducted successively from the mapping relationship between the present system and the previous system. This method is feasible and effective according to the simulation results of CE150 helicopter model. |
