摘　　要：针对调节阀工作中控制速度不平滑、容易控制超调等问题,在智能阀门定位器控制算法设计中,采用脉冲调宽控制的方式,基于"五步开关"算法,提出了对定位速度量化控制的算法,实现了算法间的无扰切换。实验结果表明:该算法有效解决了上述问题,并具有一定的自适应及鲁棒特性。The smart valve positioner as a core part of the entire control valve control system, played a pivotal role in the industrial control. Aiming at the problem of unsmooth control speed curve and o- vershoot in the valve working process in the smart valve positioner control algorithm design, and using a pulse width modulated control, this paper proposed quantization control algorithm for positioning speed on the basis of ＂5-step switch＂, achieving bumpless switching between algorithms. The experimental results show that the algorithm is effective to solve the above problems, and have the character-istics of being adaptive and robust.
