Concluding Remarks

• Cable structure of feed support can avoid the
• heavy and expensive platform
• Stewart stabilizer is able to compensate the
• displacements of the cabin and cables caused
  
• by wind impacts
• The monitoring of tension is critical for the
  safety
• of suspended cables
• High accuracy( several millimeters) with a
  rather fast sampling rate up to 10Hz for the
  future FAST.
