Target acquisition algorithm based on Sliding Mode Control (SMC) is proposed for TV tracking system. Target acquisition capability and performance are both improved  attributing to overcoming the deficiencies of traditional linear control. In this paper  sliding surface with variable coefficient and continuous control law without switching is introduced in the SMC controller design. The improved SMC shows better performance compared to basic SMC  and full-field acquisition with rapid response and non-overshoot is achieved. The simulation of acquisition shows that  the system can acquire a target passing through the view field of 1.53 in the width with an uniform speed of 15 /s  while the whole process is in a short settling time and chattering-free  and the reaching segment has no overshoot. 2010 IEEE.

Star sensor is a special high accuracy photoelectric sensor. Attitude acquisition time is an important function index of star sensor. In this paper  the design target is to acquire 10 samples per second dynamic performance. On the basis of analyzing CCD signals timing and star image processing  a new design and a special parallel architecture for improving star image processing are presented in this paper. In the design  the operation moving the data in expanded windows including the star to the on-chip memory of DSP is arranged in the invalid period of CCD frame signal. During the CCD saving the star image to memory  DSP processes the data in the on-chip memory. This parallelism greatly improves the efficiency of processing. The scheme proposed here results in enormous savings of memory normally required. In the scheme  DSP HOLD mode and CPLD technology are used to make a shared memory between CCD and DSP. The efficiency of processing is discussed in numerical tests. Only in 3.5ms is acquired the five lightest stars in the star acquisition stage. In 43us  the data in five expanded windows including stars are moved into the internal memory of DSP  and in 1.6ms  five star coordinates are achieved in the star tracking stage.
