The Synchronization Control of Gantry Machining Center Magnetic Suspension System Base on ModelReference Fuzzy Adaptive

Abstract:

For Gantry CNC Machining Center single suspension system, adopting a control strategy that combines speed position control and fuzzy adaptive control. By designing fuzzy adaptive controller to adjust the scale factors of speed and position controller in time, ensure the robustness of a single suspension system. For the double suspension system, adopt cross-coupled synchronous control strategy. By designing cross-coupled synchronous controller between the two systems, overcome suspension height deviation of the double suspension systems, restrain tilt, to achieve the synchronization suspension purpose. Simulation results show that this control scheme guarantee the system synchronization suspension and its stability. While it has strong robust, synchronization error of dynamic process is small. It can meet the requirements of high precision.
