The Modeling and Simulation of the Precision CNC Lathe Knife Tower Servo System Based on Matlab/Simulink

Based on the analysis of the PMSM’s mathematic model, we’ll use the Matlab/Simulink to construct the simulation model of the precision CNC lathe knife tower servo system. The control system uses the classical three closed structure. According to the servo system's performance requirements, we'll do the parameter selection and simulation. The simulation result proves the validity of the model and provides the theory basis for the system's design and debug.
