Abstract
We have designed an active stressed lap and its control mode is that an computer sends control orders to the control system of the active stress lap, under windows operating system. The control mode has a shortage, which is a limit exists when we use the lap to complete an aspheric surface deformation task with a fast focal ratio, because windows system is not real-time. Therefore, we have designed a real-time deformation control system for the active stressed lap. The paper makes an introduction to the structure of the deformation control system of the active stressed lap. Secondly, gives a detailed presentation on the design of the test system from software and hardware two aspects. Finally, the paper makes a dynamic response test on the deformation control system of stressed lap, a stability test on the control system and an overall performance test
