摘　　要：多电机同步控制广泛应用于工业生产中,同步控制的性能直接影响产品质量的好坏。设计了由MCU+DSP+CPLD组成的多电机同步控制平台。平台运用C语言编写了MCU与DSP部分的程序,采用VHDL硬件描述语言来书写CPLD部分的程序,从而实现了MCU对张力的高速采集,DSP对控制算法的高速运算及DSP对CPLD高速传输指令,CPLD对DSP、变频器及上位机串口的通信。平台采用基于RS-485接口的USS协议实现与变频器的通信。对该平台进行了速度响应及张力稳定为一体的试验,试验证明其可以稳定控制3台电机,且控制性能优于PLC控制,具有良好的控制性能。Multi-motor synchronous control is widely used in industrial production. The performance of synchronous control directly affects the quality of the product. A multi-motor synchronization control platform composed of MCU,DSP and CPLD was designed. MCU and DSP was programed by using C language in the platform and the part in CPLD was programed by using VHDL language. In the platform, MCU was responsible for the high speed acquisition of tension and DSP was responsible for the high speed operation of the control algorithm, transmiting instructions to the CPLD. The function of CPLD was communicating with DSP and inverter as well upper computer. The platform communicates with inverter by using USS protocol format through the RS-485 interface. A velocity response experiment combined with tension stability has been carried out by using the platform. The experimental results showed that the platform could stably control 3 motors and was better comparing with PLC in control performance.
