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.
