伺服电机控制系统，02年开始积累，效果好，速度快，PI控制，经典控制，fuzzy PID，自适应控制，速度位置控制等等，欢迎大家参考。(Servo motor control system, in 2002 began to accumulate, effective, fast, PI control, classical control, fuzzy PID, adaptive control, speed position control, etc., we welcome the reference.)

底层调用了PCSC的通信库Winscard，可用于PC上读卡器与智能卡的通信(It calls the underlying communication library Winscard PC can be used on a PC to communicate with the smart card reader)

7段数码管显示与对应值计算工具。先点击对应管位，设置显示顺序，再点击生成即可获得键值。鼠标选择键值，数码管相应显示。(7-segment LED display with the corresponding value calculation tools. Firstly, click the corresponding tube in the LED, in order to set the display order. Then click Generate to get the value. After created, select the key and the digital will show the char accordingly.)
