摘要
四旋翼直升机因其优良特性,在军事和民用领域均有广阔的应用前景。为确保其安全稳定飞行,针对周口师范学院自主研制的四旋翼直升机,结合其结构及动力学原理,考虑非匹配不确定性因素的影响,对三自由度四旋翼直升机进行建模。采用线性矩阵不等式技术进行变结构滑模控制系统设计,仿真结果表明,该系统抗参变能力较强,直升机的飞行姿态基本满足控制要求。
The quadrotor has broad application prospect in military and civil fields due to its excellent properties. In order to ensure its safe and stable flight,aiming at the quadrotor developed by Zhoukou Normal University independently,a quadrotor with three-degree of freedom is modeled in combination with its structure,dynamics principle,and effect of unmatched uncertainty factors. The linear matrix inequality technology is used to design the variable structure sliding-mode control system. The simulation result shows that the system has strong capability to resist the parameter variation,and the flight attitude of the quadrotor can satisfy the control requirements basically.
