铣钻床高速电主轴调速系统设计

Design for Motorized Spindle Speed Regulating System of High-Speed Milling and Drilling Machine

根据小型铣钻床的加工要求和特点,在分析了高速电主轴负载特性的基础上,确定了使用V/F控制方法结合空间矢量调制技术来设计调速系统。并用MATLAB中的Simulink工具箱对设计的控制系统进行仿真研究,证明了系统具有较好的控制效果。最后基于DSP芯片完成了控制系统的硬件电路设计及软件程序的编写,并对系统进行了实验研究,结果证明控制效果良好。。

The speed control system with V/F control method combines space vector modulation was designed, accord- ing to the processing requirements and characteristics of small milling drilling. And the control system was simulated with simulink of MATLAB. The control system hardware circuit was completed and the software program was written based on the DSP chip. Through the systematic experimental study, the results show good control effect.
