  • Patent number: 11809166
    Abstract: A method and system for compensating for stiction of a control valve in a pneumatically controlled valve system. A digital twin model of the pneumatically controlled valve system is generated. A current segment of data signals is received from a process measurement device connected to the pneumatically controlled valve system. Operation of the pneumatically controlled valve system is monitored by comparing the current segment to the digital twin model. Stiction is detected when the digital twin model directly detects stiction or when the nonlinearity and Gaussian index are above a certain threshold. A severity of the stiction is determined. Instructions for a stiction control device are used to generate control signals to be applied to the actuator to compensate for the severity of the stiction. Further, the digital twin model is displayed with a representation of the severity of the stiction.
