1, static control valve friction compensation High-frequency input signal can make the static friction point in different places quickly converted. Higher oscillation frequency can greatly improve the control performance. 2, semi-feedback and full feedback The location of the output signal measurement directly affects the accuracy and sensitivity of the control system, the feedback system, usually semi-feedback and full feedback. If the measurement signal is taken from the stem of the valve, it is semi-feedback, due to the elasticity of the stem and other components, creep and hysteresis and other factors, the signal does not truly reflect the valve opening. Therefore, the flow through the valve should be taken directly as the measurement signal for full feedback, and the system's accuracy and sensitivity are higher.
