METHODS AND APPARATUS TO LIMIT A CHANGE OF A DRIVE VALUE IN AN ELECTRO-PNEUMATIC CONTROLLER. |
摘要 |
Example methods and apparatus to limit a change of a drive value in an electro-pneumatic controller are disclosed. A disclosed example method includes determining a slew limit of a controller based on noise in at least one of a control signal or a feedback signal, calculating a drive value based on the control signal and the feedback signal, and changing the calculated drive value if a difference between the drive value and a previous drive value is greater than the slew limit of the controller. |
