Airborne Patrol Missile Btt Controller Parameter Design

Nowadays, it is an important trend that cruise missiles are and will be new air-to-ground weapons in the development of information ammunition. Moreover, airborne cruise missile is one of the core weapons which Air Force can attack any ground targets accurately and efficiently in future information war. With the difference of conventional guided bombs, cruise missiles can undertake various tasks at the same time, such as reconnaissance, damage assessment, the radio relay, target designation, air alert, precision strikes, etc. As an important component of the system of airborne cruise missile, the design of BTT control system will directly influence the performance of cruise missile. Therefore, In order to provide references for further engineering research on airborne cruise missiles, paper will take its BTT controller system for the research object, design the BTT controller parameters, and make digital simulations.The main research points done for the dissertation are listed as follows:1. Scheme trajectory design and dynamic analysis.According to the operational requirements of the cruise missile, BTT scheme trajectories have been designed respectively during the flying ballistic, such as stable section, gliding, straight flying and reconnaissance patrolling. On the bases of the small perturbation theory, the dynamic characteristics of the cruise missile have also been taken into analysis.2. Design and Study on the BTT autopilot for cruise missiles.Models of the transfer function of cruise missiles have been established by the typical feature points selected in the solution trajectories. Moreover, on the methods of classical PID control, the BTT autopilot parameters have been designed respectively for three-channels of Cruise missiles, such as pitch and yaw, roll.3. Study on decoupling control of the Pitch/yaw channel.The decoupling controller of variable structure in pitch/yaw channel of the cruise missile have been designed, by the way that the pitch/yaw coupling channel were taken as interference and the invariability principle of the variable structure control for interference. Digital simulation showed that the decoupling effect on the BTT controller system was obvious.4. 6DOF ballistic simulation for cruise missiles.Firstly, Digital models for space 6DOF of the cruise missile have been established. Secondly, based on the design of BTT autopilot and decoupling controller, the 6DOF Digital simulations have been made. And the simulation results showed that the BTT control system can work normally, meeting the general requirement for the flight control of cruise missiles.
