摘要: 从提高驾驶员操纵控制飞机的跟随性能和减轻驾驶员的操纵负担出发,提出了预测引导指示信号综合的结构和实现方法,其特点是驾驶员能够只需采取增益加延时的操纵控制特性,在预测决策操纵指示的引导下完成高性能的飞机跟踪控制任务.通过旋翼飞机变空速地形跟踪任务的指示信号综合研究,提出了由空速控制回路耦合干扰观测器的设计消除其对驾驶员高度控制影响的方法.Abstract: In order to improve the pursuit property of flight by pilot and to relax pilot's workload, the structure and realization methods of predictive directing signal synthesis were proposed. With the realization of these methods, pilot can use gain plus time delay control characteristics and fulfill high quality tracking flight task under the display of predictive operation signal. In the predictive directing signal synthesis research for rotorcraft terrain following task, a method to eliminate the coupled effect of airspeed loop through coupled disturbance observer design was also proposed. The validity of these methods were demonstrated by simulations.
