Abstract :
The need for precise fast positioning technique draws attention on space inter-satellite optical communication. This paper presents a novel PZT actuated precise tilt positioning system (PTPS), which consists of the control module, the PZT driving module, the precise tilt positioning mechanism (PTPM), and the precise displacement measure module. It provides a fast and precise control in tilt movements. Firstly, the structure analysis and design of PTPM are accomplished. Then the control module is developed and the current/ voltage composite driving method is investigated in detail. Finally, following the experimental results which confirm the validity of the design and theoretical analysis of the PFPS.
