A novel controller module based on DSP and CPLD is introduced according to the characteristic and requirement of servo control system. The hardware and software are discussed in detail. The high-speed DSP is acted as core for digital servo controller. The CPLD is adopted to achieve peripheral signal processing and control for logic and sequence. A function library is built according to C++ class structure and can be applied randomly. The experimental results show that the controller has the advantages of high reliability, opening structure, simple operation and can be applied with flexibility according to engineer requirement.
