The mathematic model of the motor is built,and the servo method of linear motor with MF type is researched,which is composed of a double close d-loop controller based on P-D control presented to improve the performance of d isturbance rejection,a magnitude and phase regulating controller and a feedforw ard error compensate scheme proposed to meet the.

As a result of these,a microwave circuit by numerical control using the amplitude and phase shift adjusting has been de-veloped.

Flatness feed-forward control based on measured values of incoming strip profile

In this paper,we have discussed the problem of u- sing multisection NC code first gazes optimized processing to implement the feed-forward control of CNC machine based on control theory,thus it can constantly adjust the feeding speed based on different curvature radius in the shortes.

Automatic adding flocculent is effected through feed-back control and feed-forward control of automatic adding flocculent solving liquid.
