3.1 PLC的选择
根据系统需求，结构简单，低功耗，功能强大等特点，由S7-200系列可以用作控制器，这类PLC可以分为两种类型，基础型和扩展型。基础型包括CPU221，CPU222，CPU224和CPU226。CPU226拥有40个独立的管脚（24个输入端，16个输出端） 还有 2个RS485端口，它支持诸如PPI，FREE等。利用这些资源它可以与计算机，PLC和打印机进行通讯，256的时间控制器，256的计算器，256的内延时还有2400的特殊功能寄存器，因此它可以实现复杂的过程控制。基于以上优点我们选择226作为控制器。
反馈信号的检测：
来自电机的反馈电流信号是控制系统中的重要数据。它的检测精确程度直接影响着控制效果。转动速度检测电路和激发电流检测电路的原理和磁场电流检测的原理是相似的。

3.1 PLC
According to the system requirement, simple structure, low power consumption, powerful features, by S7-200 series can be used, this kind of PLC controller can be divided into two types, foundation and extension. Basic type, including CPU221 CPU222 CPU224, CPU226 and. CPU226 have 40 independent tube feet (24 input and output 16) and 2 RS485 ports, such as copy, it supports PPI, etc. Use these resources with computer, PLC, it can communicate with printers, 256 time controller, 256 calculators, inside the delay and 2400 256 special function, so it can realize the register of complex process control. Based on the above advantages we choose 226 as controllers.
Feedback signal detection:
The feedback from the electric current signal is the important data control system. Its detection accuracy control effect directly influences. Rotating speed detection circuit and inspire current detection circuit principle and magnetic current detection principle of which is simila
