High-Speed Motorized Spindle Decoupling Optimization Control

Article Preview

Abstract:

High-speed motorized spindle is the core component of the CNC machines. Its dynamic performance directly affects the accuracy of the geometry, and be the root cause of vibration, noise and temperature increase, etc. Its motor control system has the characteristics of nonlinear and strong coupling, which is one of the key R&D items of the spindle design. Based on granular computing, this paper selects the appropriate granularity to analyze the coupling between the motor control parameters and system performance, and propose a zoning decoupling and optimization method to optimize the overall system performance, which has practical application value.
