The Controller Design And Simulation Of A Certain Unmanned Aerial Vehicle

In recent years, with the development of technology, the unmanned aerial vehicle(uav) industry developed so fast and we can see it more and more in Aerial, geological survey, forest fire, pesticide spraying and communications relay, local war and so on. The stability control for unmanned aerial vehicle(uav) flight is the premise to guarantee complete the task perfectly, for a particular aircraft, design a performance controller is an important subject.In the view of complexity of local war environment, Choose a suitable aircraft for soldiers,it can be used to investigation the enemy reconnaissance or suicide attacks, which provide necessary support for the soldiers occupied the battlefield advantages.In this paper,we first studies the current situation of the development of unmanned aerial vehicle, To understand the development trend of the unmanned aerial vehicle and Comprehensive analysis the existing method of flight control which provide reference for the controller design.Then use flight mechanics and aerodynamics to established the mathematical model of unmanned aerial vehicle,Using the MATLAB software to linearize the mathematical model of unmanned aerial vehicle and obtain the state space equation which is the base for design the controller.Considering the unmanned aerial vehicle longitudinal movement and lateral movement coupling less, so we can design the longitudinal and lateral controller respectively in the third and fourth chapter, at here designed two cotrollers for each movement,they are the classic controller and intelligent controller.Finally combining with the above design the controller of uav autonomous flight, Because the straight line and circle is composed of complex flight track elements, So this chapter mainly analyzes the straight trajectory tracking control and circle track control.
