Design of the motorized spindle temperature control system with PID algorithm

Abstract

The thermal error of the motorized spindle has great influence on the accuracy of the NC machine tools. In order to reduce the thermal error, the increase type PID control algorithm is adopted for the control system which can make the temperature controlled in reasonable range. In accordance with the control object features, the Application of the control algorithm is realized in MCU System. Finally, the experiments are carried out which verified the validity and effectiveness of the design of temperature control system by analysis of the experimental data.
