With the development of modern satellite reconnaissance technology,the frequency and accuracy of reconnaissance are constantly improving,and the vehicle-mounted missile launching combat platform is easily exposed.In order to win in modern war,it is required that the weapon missile system should have good mobility and rapid response ability.As far as missile launchers are concerned,the most effective way to improve maneuverability and rapid reaction is to shorten the preparation time for missile launches.The missile erection time accounts for 1/5～1/3 of the missile preparation time,so it is particularly important to shorten the missile erection time.How to shorten the missile erection time has become the focus of research in the field of modern missile launching technology.This paper takes large missile erecting system as the research object,including the following aspects of rapid erecting technology research.(1)According to the technical requirements of a missile launch vehicle,the key parameters of the load are calculated,and the structure of multistage hydraulic cylinder is designed.A set of rapid erecting system based on gas-liquid hybrid power source is proposed.The system used closed electronic control pump as the main power source and accumulator as the auxiliary power source.The method of constant power trajectory planning is used to plan the vertical Angle,the key parameters of the main and auxiliary power sources are calculated,and the key components are selected.Finally,the oil source system of the closed electronic control pump is tested.(2)The nonlinear mathematical modeling of rapid erecting system based on gas-liquid hybrid power source is presented.Firstly,the nonlinear mathematical model of the mechanical subsystem of the rapid erecting system is established,and then the nonlinear mathematical model of the hydraulic subsystem of the rapid erecting system is established.(3)Firstly,a fuzzy PID controller with simple implementation is designed.Then,a nonlinear integral robust controller(RISE)is designed based on the nonlinear mathematical model of the rapid erector system based on gas-liquid hybrid power source,and the stability of the designed nonlinear controller is proved.(4)The co-simulation model of rapid erecting system based on gas-liquid hybrid power source is established,and the superiority of nonlinear integral robust controller is verified by the co-simulation.
