摘要:智能电-气阀门定位器是阀门执行机构的核心控制部件,智能阀门定位器的控制算法与控制参数的选择直接决定着定位器的性能。针对阀门对象的时变性和非线性的特性,把仿人智能控制应用于智能阀门定位器,完成了仿人智能控制器的运行控制级与参数矫正级的设计。智能阀门定位器的自检过程完成对阀门特征的辨识和仿人智能控制的参数整定,并对气体泄漏采取补偿措施,有效减小了气体泄漏所造成的不利影响。仿真与应用结果表明了该算法的有效性。

Abstract:Smart electro-pneumatic valve positioner is the most important element of intelligent pneumatic actuators. The selection of the control arithmetic and the parameters decides the positioning performance of the pneumatic valve positioner directly. Aiming at the valve positioner, which has the characteristics of time-variation and nonlinear, HSIC (Human-Simulated Intelligent Control) is applied in the smart pneumatic valve positioner, and the operating control level design and parameter adjusting level design of the HSIC controller are plished. The identification of the characteristic of the pneumatic valve and parameter setting of HSIC pleted in the self-test process of the smart pneumatic valve positioner. Compensation measure for gas
