Title Design and simulation of a missile booster thrust
vector control loop
Abstract
This paper is on the design of thrust vector control with the spoiler system for vertical launching .Based on the spoiler, missile model with six degrees of freedom was designed using Simulink computational method，and Mathematical model of longitudinal disturbance in the loop for turning control was derived and conducted with frequency domain analysis. To get the feasible vertical launch turning law, a optimization algorithm which combines PSO with GA was employed to seek.
Then, a hardware control panel using the stm32 mcu was to realize some functions, such as wireless command signal transmission, user interface, digital to analog conversion and so on. To ensure the real-time performance, the software development environment on this chip board is based on μC/OS-II operating system and μC/GUI graphics system. The control panel receives the command signals of turning angle of the spoiler, and pass the current signal of 4-20mA to drive a proportional solenoid valve through a amplifier. The opening degree of Proportional solenoid valve cause The motion of spoiler which produces aerodynamic for turn control.
