The Design and Simulation of Missile Internal and External Loops with Dual PID Control

A class of height double PID controller based on posture stability is designed in this paper aim at simplified dynamics model of missile pitch channel linearization and simplified model of missile height kinematics link. The implement process of using matlab software simulink toolbox is introduced in detail. Secondly, The transfer function calculating algorithm which solves nonlinear link in simulink using matlab language linmod function is proposed in this paper aim at nonlinear of height kinematics link. Finally, the bode diagram of whole system is obtained and the stability margin of system is analyzed by computer simulation.
