Abstract: Two kinds of acceleration and deceleration methods commonly are used for speed turntable.One is the straight line acceleration and deceleration method,the other is the exponential acceleration and deceleration method.Both of the two methods have mutations of acceleration,and there will be an impact for the test equipment. S-shaped curve acceleration and deceleration method for speed turntable is discussed in this article,which will ensure full performance of motor and can effectively reduce the mutations of acceleration,thus rapid and smooth operation can be achieved.In addifion, a control algorithm for computer is designed.
