Abstract
矢量控制和直接转矩控制是高速电主轴的高性能驱动控制方法，其控制性能对高速电主轴的加工质量有重要影响。为了研究高速电主轴的矢量控制、直接转矩控制以及它们之间的差异，本文根据其控制基本方程，分别建立一个矢量控制仿真模型和一个直接转矩控制模型，对额定转速为15,000转的170MD15Y20型高速电主轴进行了矢量控制和直接转矩控制仿真，并对仿真结果进行了分析、对比，最后总结了矢量控制和直接转矩控制的特点。 Vector control (VC) and Direct torque control (DTC) are both high-performance drive control methods for high-speed motorized spindles, and their control performances have a significant impact on the machining quality of the spindle. To study VC, DTC and their comparison on high-speed motorized spindles, according to their basic control equations, a VC model and a DTC model are constructed respectively to carry out VC and DTC simulation on a type 170MD15Y20 high-speed motorized spindle, whose rated speed is 15,000 rpm. The simulation results are analyzed and compared, and the features of VC and DTC are summarized.
