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.
