Patent number: 10337647Abstract: A system receives a plurality of data samples associated with a control valve with each of the plurality of data samples associated with a setpoint and a position. A first subset of the data samples that are in a control zone associated with normal operation of the control valve is determined. In a case that a second subset of the data samples are determined to be (i) not in the first subset and (ii) close to a minimum position of the plurality of data samples and (iii) have setpoints less than their associated positions, an alert associated with a low obstruction is indicated. In a case that a second subset of the data samples are determined to be (i) not in the first subset and (ii) close to the maximum position of the plurality of data samples and (iii) have setpoint greater than their associated position, an alert is indicated.Type: GrantFiled: November 30, 2015Date of Patent: July 2, 2019Assignee: General Electric CompanyInventors: Frederick Wilson Wheeler, Justin Scott Shriver, Larry Gene Schoonover, Brett Alexander Matthews
