Design And Simulation Of A Domestic Anti-UAV Missile Control System

With the rapid development and continuous popularization of drones,it has been widely used in various fields.At the same time,its potential safety hazards have gradually been exposed,and it is being used by some users without professional training and some illegal users.It is very likely to pose a huge threat to public property and personal privacy as well as the lives of citizens.In order to deal with these threats,it is necessary to develop a low-altitude anti-UAV missile defense system,which can attack low-altitude or ultra-lowaltitude intrusion air targets(UAVs).This article focuses on modeling,analysis and design of the control and stability system of this low-altitude missile defense system.The main contents are as follows:This article first establishes the coordinate system of the low-altitude defense missile,and analyzes the dynamic model of the low-altitude defense missile.According to the force analysis of the low-altitude defense missile,the body kinematics equations and the body dynamics equations of the low-altitude defense missile are derived,and the four angles of attack angle,sideslip angle,ballistic inclination and ballistic deflection angle are established.Calculation model.Completed the establishment of the mathematical model of the kinematics and dynamics of the low-altitude defense missile.The solidification principle and the hypothesis of small disturbance are adopted to convert the mathematical model of the missile into a linearized equation system.Secondly,based on the analysis of the aerodynamic configuration of the missile,the aerodynamic parameters of the missile are obtained through calculation and measurement.On the basis of the mathematical model,the transfer functions of the three channels of pitch,yaw and roll are established,and the PID algorithm Based on the analysis and comparison,the three-channel control law was designed to enable the low-altitude defense missile to fly to the target stably during the entire flight,achieving the expected design effect.Finally,Matlab is used for simulation design and the simulation results are analyzed.The three channels of pitch,yaw and roll of this low-altitude defense missile during flight were simulated to stabilize the attitude of the missile.The final simulation results show that this article has achieved the expected requirements in the process of missile control.
