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 operatingcontrol level design and parameter adjusting level design of the HSIC controller are accomplished. The identification of the characteristic of the pneumatic valve and parameter setting of HSIC are completed in the self-test process of the smart pneumatic valve positioner. Compensation measure for gas leakage is adopted to reduce the harmful effect caused by gas leakage. Simu...
