This article studies a kind of grinding wheel dynamic balance control device sliding variable structure controller based on the grinding wheel dynamic balance observation system mathematical model. It has proposed a new kind of method for improving the dynamic performance of balance block control system, which applies variable structure control theory and(More)
This article studied the signal reconstruction algorithm of unbalanced vibration signal under strong disturbance background based on weight load balancing principle. Using the precise spectrum analysis method, we can carry out signal reconstruction and obtain the true value of grinding wheel unbalance quantity. Given a kind of unbalanced signal extraction(More)
To satisfy the need of high precision numerical control machining, the 5 stage S-type acceleration/deceleration control model is proposed, and the model is established under two conditions of without considering transient acceleration and transient speed and considering the startup acceleration and the transient speed respectively. In order to obtain an(More)
