Simulation Results

Aiming at the problems of disturbance, coupling and fluctuation of load existing in permanent magnet synchronous motor (PMSM),which is used in the servo system of self-propelled gun, the auto disturbance rejection control technique (ADRC) is introduced into in the servo system of self-propelled gun. It can play with the best effect of the servo control system. The simulation results show that ADRC makes the servo system of self-propelled gun has better accuracy and robust.

Slub Yarn

High-precision slub yarn can be produced by EJM128K type ring bobbin equipped with servo control system which has the characteristic of stability ,precision and rapidity to control slub length by analyzing the transfer function of it. The length of slub yarns was tested with USTER® TESTER5, and the distribution curve of slub length and slub space can be attained. The gauge of between front and middle roller affects slub length deflection. This result can control effectively slub length and produce high-class slub yarn.

Embedded Technique

Designing a high quality and low cost servo control system of micro-EDM is the key technique of high precision micro-EDM. The paper solves this problem by designing an embedded servo control system of micro-EDM. The servo system realized the FOC of PMSM by using embedded technique, which connect the servo controller and the pulse generator properly. The scheme of servo control system has the merits that it is low cost, flexible and self adjustment of discharging gap.
