摘要
针对倾转旋翼机独特的气动构型和复杂的气动特性带来的横航向通道强耦合问题,首先以XV-15倾转旋翼机为研究对象,建立其横航向数学模型,其次从定性和定量2个角度分析横航向通道的飞行特性与耦合特性。为保证倾转旋翼机直升机模式的飞行安全与控制性能,提出采用隐模型跟踪控制与经典PID控制相结合的方法进行横航向通道内外环控制律设计。最后基于MATLAB/Simulink搭建倾转旋翼机飞行控制仿真系统,将所设计的横航向通道控制律与常规PID控制方法进行仿真验证与对比分析。仿真结果表明,相比于常规PID控制,该控制系统可以实现横航向通道解耦控制,并具有更好的稳定性与动态响应特性。
In response to the strong coupling problem of the lateral and heading channel caused by the unique aerodynamic configuration and complex aerodynamic characteristics of tiltrotor aircraft,this paper first takes the XV-15 tiltrotor aircraft as the research object and establishes its lateral and heading mathematical model.Secondly,the flight characteristics and coupling characteristics of the lateral and heading channel are analyzed from both qualitative and quantitative perspectives.To ensure the flight safety and control performance of the tiltrotor helicopter mode,this paper proposes a method of combining implicit model following control with classical PID control for the design of control laws for the inner and outer loops of the lateral and heading channel.Finally,a tiltrotor aircraft flight control simulation system is built based on MATLAB/Simulink.The lateral and heading channel control law designed in this paper is verified and compared with the conventional PID control method through simulation and analysis.The simulation results show that compared with conventional PID control,this control system can achieve decoupling control of the lateral and heading channel and has better stability and dynamic response characteristics.
