发明名称 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 receiving a control signal and a feedback signal, calculating from the control signal and the feedback signal a drive value, determining if a difference between the drive value and a previous drive value is greater than a slew limit of the electro-pneumatic controller, and changing the calculated drive value based on the slew limit.
