The design of speed feedback in a digital AC servo control system;

Controlling spatiotemporal chaos by speed feedback method

In this paper, some methods for realiaing speed feedback are analnd .

The substance of the Skyhook control is discussed and a new semi-active vibration control strategy based on acceleration feedback and velocity feedback is established.

The experiment shows that, no matter how the supporter is excited, harmonically or randomly, its vibration may effectively be suppressed by using piezoceramic material as sensors and actuators to achieve velocity feedback controlling.

By means of velocity feedback control agolrithm the active vibration control of laminates is fulfilled.

The paper introduced mathematical model of S type of three-segment speed setting in main shaft hoist system,and designed its simulation model based on Matlab/Simulink and gave out the simulation result.

After analyzing the feed rate in numerical-controlled machining,this paper introduces the working principles and advantages of the toolpath optimization model of the software,and presents the actual process of optimizing toolpath in VERICUT.

According to the characteistics of cold ring rolling and the working theory of cold ring rolling mill,four kinds of feed rate design were offered.

Feed rate optimization for the rough machining means that it takes maximum machining efficiency as object function, it takes maximum main power and so on as limitation, feed rate in different stages are automatically adjusted according to optimization parameters designed by customers to keep maximum main power in a constant state, which makes material removal rate maximum.
