analyzing the system
Firstly, overall program has been presented through deeply analyzing the system functional index, which includes a three-axis stabilized platform based on electronic compass, gyroscopes and stepping motors. This system also establishs the closed-loop feedback stabilized control method, which is based on the speed (gy...更多roscopes' outputs), position (electronic compass' output) and AGC value.Secondly, the design of three-axis stabilizing and tracking mechanical structure has been ascertained, as well sensors and motors which is fit to this system. The method of picking AGC value, which is adapted to the system, has been ascertained through analyzing and comparing several different AGC value picking methods.Thirdly, according to the said design goal and functional requirements of the system, the method of modular design has been adopted and the controller based on the control chip of high-performance DSP TMS320F2812 has been designed ,as well the achievement of PCB board.At last, the system's software module, which is matching the hardware module, has been designed and debugged, the results confirm the feasibility of the design program of the system controller. An improved program has been presented according to the problems generated from the process of system debugging.
