Abstract
This paper proposed an innovative real-time embedded control system for satellite scanning mirror mechanism. The mechanism element was assembled with two supporting pivots on the axis with an angular sensor and a voice motor accurate. The control precision of the scanning mirror is stringent in space remote target detection, at the same time angle position of the equipment was required to send to ground on time. The implementation of the embedded hardware and algorithm system are described in steps. The scanning mirror mechanism with voice-coil motor is identified and a forward feedback control topology is been described to realize the position trajectory control of the prototype. The prototype mechanism using the BMTI microcontroller 32 bit for the voice-coil motor control is exhibited. A real-time bidirectional data exchange between the microcontroller and the computer with user definition protocols 422 electrical bus is presented.
