Control System Magnetic Suspend Bering for Eleetrieal Spindle of Bore Grinder

In order to solve industrial application problem of control system for magnetic sus-pend bearing spindle of the bore grinder, the PID simulation controller has been designed making use ofoptimizing control theory of linear quadratic type. By study and experiment of MATLAB software, the sta-ble operation of the magnetic suspend bearing spindle of bore grinder is realized in laboratory. The appli-cation experiment has been made in factory environment, the result shows that control system for magneticsuspend beating spindle of the bore grinder has preliminarily met the need of industry application in someperformances such as the spindle rotation speed, operation accuracy, grinding rigidity and stability etc.
