摘要
分析了飞行器被控对象的特性,针对被控对象的特性对设计过程、设计方法和控制特性进行了系统分析,详细推导了几种常用控制结构的利弊,再针对飞行器飞行特点设计使用了三回路控制结构。在飞行过程中会出现静中立稳定和静不稳定的问题,文中所用的控制结构很好地解决了飞行过程中静不稳定问题,消除了常值舵机零位误差的影响,稳态传递系数不受气动参数变化的影响。
The characteristics of the aircraft controlled object are analyzed.According to the characteristics of the controlled object,the design method and control characteristics of the design process are systematically analyzed.The advantages and disadvantages of several common control structures are derived in detail,and the three-loop-control structure is used to design the flight characteristics of the aircraft.The static neutrality stability and static instability can occur during the flight.The control structure used in this paper solves the static instability control problem well,and eliminates the influence of the zero position error of the constant value rudder,and the steady state transfer coefficient is not affected by the change of aerodynamic parameters.
