中文摘要:
      针对过程工业对气动调节阀的控制精度与稳定性有较高要求, 而常规 PID 控制策略自适应性与实时性 差,难以取得较好的控制效果的问题,根据 GM(1,1) 模型灰色作用量具有的动态特征来改进灰色预测模型,结合改 进灰色预测控制与模糊 PID 控制的优点,提出了改进灰色预测模糊 PID 控制策略.仿真结果表明: 改进控制策略明 显优于常规 PID、模糊 PID、灰色预测模糊 PID 控制策略,使系统响应速度加快,超调量减小,且适用于不同的阀门 定位系统.
英文摘要:
      For high demand to the control precision and stability of the pneumatic control valve in the process industry, with poor self-adaptability and real-time performance, the traditional PID control strategy is hard to achieve good control effect.The grey action based on the GM( 1,1) have dynamic characteristics. Combining with the advantages of improved grey predictive control and fuzzy PID control, which put forward the improved grey prediction fuzzy PID control strategy. The simulation results show that this strategy possess better control performance compared with the traditional PID, fuzzy PID, grey prediction fuzzy PID control strategy, which response velocity improved and overshoot is decreased for applying to different valve positioning system.
