基于VHDL语言的直流电机控制器及其控制，本控制系统的总体结构,下位机是整个高频疲劳试验机控制器的核心。用于实现产生控制试验机的控制信号和数据，反馈信号的处理，以及和上位机进行数据通信。其控制功能强弱也直接影响着整个控制器性能的好坏-DC Motor Based on VHDL controller and its control, the overall structure of the control system, the next bit machine is the high-frequency fatigue test machine controller core. Control the testing machine used to implement the resulting control signal and data processing of the feedback signal, and the host computer and data communication. The strength of its control functions have a direct impact on the performance of the controller is good or bad
