Title Inpidual type rocket simple self-tuning PID flight control research
Abstract
Inpidual rocket is a weapon to kill your high efficiency,it has the advantages of cost-effective,easy to carry,but its beyond effective range precision is reduced,spread will become large,which requires the use of control technology in order to greatly improve the accuracy of rocket. Based on certain inpidual rocket as research object,this paper designed a simple self-tuning PID controller. In the common system,inpidual rocket flight mechanics model is established,the design scheme of flight trajectory,the small disturbance theory and coefficient freezing method to simplify the mathematical model of inpidual rocket,the disturbed motion mathematical model,so as to deduce the transfer function of ballistic missile body.Bode drawing,according to the transfer function of PID control parameters tuning,using Simulink simulation,the analysis of simulation results,we can find that the building of mathematical model is correct, the controller design is reasonable,the control effect is good,the design is verified by the inpidual type of rocket feasibility of simple self-tuning PID control system.
Keywords Inpidual rocket Outside ballistic model Self-turning PID control Simulation
