摘　　要：正交编码器广泛应用于运动测量及控制系统,在详述正交编码器角位移测量及编码工作原理基础上,设计正交编码器的X2和X4模式解码系统,并基于CPLD通过Verilog HDL描述实现解码逻辑。实际测试应用表明,该系统精度高、纯硬件抗干扰能力强、接口方便、占用逻辑宏资源少,具有较高的实用价值。Quadrature encoder is widely used in the motion measurement and control system. On the basis of detailing angular displacement measurement and encoding working principle, the quadrature encoder＇s X2 and X4 mode decoding system are designed, and the decoding logic is described and realized by the Verilog HDL based on CPLD. The actual test application shows that the system is not only equiped with high precision, anti-interference ability as pure hardware, and convenient interface, but also with occupying fewer logic macros, which will hold a high practical value.
