摘　　要：带钢冷连轧卷取机对中控制系统是轧钢设备的重要组成部分,采用传统的PID方法控制精度不高。针对这一问题,提出了动态权重差异演化PSO优化PID算法,在FPGA平台上采用并行性和状态机的设计方法对算法进行优化,利用VHDL语言在QUARTUSII中编写各个模块,得到仿真结果。结果表明,该设计方法能达到系统的预期精度要求,使系统更快速、更稳定地运行。Cold rolling strip curl machine control system is an important part of rolling equipment,and using the traditional method of PID control cannot achieve high accuracy.To solve this problem,a dynamic weight differential evolution PSO optimized PID algorithm was proposed,the design method was optimized on a parallel FPGA platforms by using state machine algorithm,various modules were prepared via QUARTUSII VHDL language,finally,the simulation results were obtained.The results show that the designed method can achieve the desired accuracy requirements of the system,make the system faster and more stable.
