摘要
文中针对倾转旋翼机拉力矢量/气动力组合控制的特点,在完成倾转旋翼机建模的基础上,采用滑模变结构控制对飞行控制系统进行了设计。提出了一套利用俯仰角、俯仰角速度构造爬升角、爬升角速度以解算滑动超平面方程的工程可实现方法,并针对变结构控制的颤振问题,给出了工程消颤算法。最后,通过仿真验证了所设计的控制系统具有良好的动态性能,具有较好的工程参考价值。
Considering the characteristics of the thrust vector/aerodynamic force multiple control for tiltrotor aircraft, this paper,based on the model of the tiltrotor aircraft, designs the flight control system using variable structure control with sliding mode.And an actual realization method, using the pitching angle and pitching angular velocity to construct rising angle and rising angular velocity,was proposed to solve the sliding surface equation.In addition,it is given an engineering algorithm for reducing the chattering,which usually exists in the variable structure control system.Eventu- ally,it is proved by simulation that the control system appears good in the dynamical performance and has a better value for engineering reference.
