摘要 针对高超声速飞行器飞行过程中因干扰造成的飞行轨迹散布问题,提出了采用飞行器飞行轨迹的模糊控制设计方法。方法以高超声速飞行器飞行轨迹线偏差和线偏差变化率作为模糊控制器输入,采用模糊推理设计飞行控制系统。在完成高超声速飞行轨迹控制系统数学建模的基础上,结合自动驾驶仪特点对飞行轨迹模糊控制系统进行了设计。结论通过仿真表明所设计的飞行控制系统满足飞行轨迹及攻角性能要求,验证了方法的正确性。 A new method of design hypersonic vehicle trajectory tracking system using fuzzy control is presented to overcome the disadvantage of flight trajectory distribution caused by separation disturbance. In this method the flight trajectory error and error ratio have been used as the input of controller. In the first part, the model of the flight traj- ectory system is given, then, the method of designing the flight trajectory system by using fuzzy is demonstrated. Fi- nally it is proved that this flight trajectory control system can assure the performance of the flight trajectory by simulation.
