复杂环境下航迹快速规划是智能飞行器控制的一个重要课题,本文通过多约束条件下智能飞行器航迹快速规划进行了研究,提出了解决飞行器由于自身定位系统受到限制和误差校正点可能失效情况下最优航迹规划的方法。通过运用基于多标号修正法(Multi-Label Correcting Algorithm)的快速最短路算法(SPFA),建立了带转弯约束的双目标航迹规划模型。该模型对由飞行器飞行环境随时间发生动态变化带来的校正误差有一定的适应性。通过仿真模拟,模型有良好的推广性,计算时间短且稳定。本研究为智能飞行器的快速航迹规划及控制,乃至误差校正点的位置设立提供了一定的参考。 相似文献

知道无人机的位置以及高度是非常重要的。知道无人机的位置就能够调整无人机的飞行过程,从而防止其坠毁,所获得的数据能够在地图上显示无人机的位置。要计算目标飞行器的位置,知道其海拔高度也是必要的。本文为四旋翼飞行器选择一种合适的定位方法,将GPS和气压计结合在一起,GPS传感器是用于在水平平面内的定位,而气压计则用来确定飞行器的海拔高度。该方法已经在派诺特AR.Drone飞行器上进行了测试,实验和仿真结果表明能够满足设计要求。 相似文献

A new robust fault-tolerant controller scheme integrating a main controller and a compensator for the self-repairing flight control system is discussed. The main controller is designed for high performance of the original faultless system. The compensating controller can be seen as a standalone loop added to the system to compensate the effects of fault guaranteeing the stability of the system. A design method is proposed using nonlinear dynamic inverse control as the main controller and nonlinear extended state observer-based compensator. System robustness is greatly improved by using the new configuration controller. The stability of the whole closed-loop system is analyzed. Feasibility and validity of the new controller is demonstrated with an aircraft simulation example. 相似文献

This paper addresses the issue of reliable feedback control of an uncertain aircraft flight control systems with disturbances via non-fragile sampled-data control approach. In particular, the parameter uncertainties are assumed to be randomly occurring which is described by the Bernoulli distributed sequences. By constructing a suitable Lyapunov–Krasovskii functional together with Wirtinger-based inequality, a new set of sufficient conditions in terms of linear matrix inequalities is obtained to ensure the asymptotic stability and extended dissipativity of the aircraft flight control systems not only when all actuators are operational, but also in case of some actuator failures. Finally, simulation results are conducted to validate the effectiveness of the proposed control design technique. 相似文献

This paper focuses on automatic climbing control methods for large civil aircraft. The key technique is how to design automatic flight control laws that meet the requirements of flight performance indexes and have good characteristics of restraining various disturbances. The classical engineering methods are used to solve the above problem. Based on the aerodynamic data of Boeing707, a nonlinear model of large civil aircraft is established. Linear models which are divided into longitudinal and lateral equations are obtained by trim and linearization. The design of longitudinal control laws uses C? criterion, three climbing schemes including pitch control mode, vertical velocity control mode and altitude control mode are designed and mutually compared. For lateral control problem, by the feedback angle of sideslip, the bank attitude control with good effect is achieved. The simulation results indicate the designed control laws can meet the requirements of performance indexes, and have satisfied characteristics of anti-gust disturbance. 相似文献
