A 450mm diameter active stressed lap has been developed in NIAOT by 2003. we design a new lap in 2007.This paper puts on emphases on introducing the new deforming control system of the lap .Aiming at the control characteristic of the lap ,a new kind of digital deforming controller is designed. The controller consists of 3 parts: computer signal disposing 、motor driving and force sensor signal disposing. Intelligent numeral PID method is applied in the controller instead of traditional PID. In the end , the result of new deformation are given.
