The Pid Control And Intelligent Pid. Flight Control Technology

As great benefits are got from the applications of UAV (unmanned air vehicle), especially the applications in military field, more and more attention is paid to the development of UAV in the world. To accomplish the complicated missions safely and effectively, there must be an advanced flight control system. Therefore the research work of UAV's flight control must be enhanced .The thesis adapts traditional PID control and intelligent PID control theories to study the design of UAV's fight control law.Firstly, the UAV's math model is built. We get nonlinear differential equations in 12 first-order , which is six-degrees-of-freedom(6-DOF) model.Secondly, the thesis introduces theoris and means of traditional PID and intelligent PID control. And I study how to adapt intelligent PID control to UAV's flight control.Thirdly, the constitute and control scheme of the lognitudinal control system is studied. Then, traditional PID control and intelligent PID control is respectively used to design and simulate the laws of pitching pose holding mode and high holding mode.Lastly, the constitute and control scheme of the lateral control system is studied. Traditional PID control is used to design and simulate the laws of slope pose holding mode, course pose holding mode and harmony swerve mode.The simulation results indicate that the routine PID flight control laws we design are effective,and the intelligent PID flight control laws are more effective.
