摘要： The present invention discloses a machine-accessible medium having instructions stored thereon that, when executed, cause a machine to receive a control signal and a feedback signal as well as to calculate from the control signal and the feedback signal a drive value. Furthermore the medium calculates a slew limit based on at least one or more of the drive value, the feedback signal, the control signal, and a noise level of the feedback signal, whereby the slew limit can change according to the state of the drive value, the feedback signal, the control signal and/or the noise level. The method further determines if a difference between the drive value and a previous drive value is greater than the calculated slew limit of an electro-pneumatic controller; and changes the calculated drive value based on the slew limit.

摘要： A valve (10) positioner system (12) that includes one or more unique control methods and devices, including several routines (80) to facilitate the continuous maintenance, calibration and adjsutment requirements of the valve. The positioner system may utilize pressure and position feedback signals (42) to monitor the valve. The positioner system may utilize an external controller (18) for various diagnostic and other routines (80). The positioner system (12) can provide automatic positioning and can operate in a manual operating mode or an automatic operating mode. The positioner system (12) can diagnose the valve while the valve process is running or during a maintenance operation. The positioner system (12) can provide nonlinear control of the valve position. The positioner system (12) can self-tune and self-characterize the valve to assure uniform position control. The positioner system (12) can provide valve control through pressure feedback (40) when a position feedback (42) fails or other diagnosed problems. The positioner system (12) can provide constraints to prevent slope reversal or slope changes in the valve characterization that would produce undesirable valve gain.

摘要： A pneumatic control system for machines that provides precise incremental or continuous direction, position, veloc- tty and acceleration control of a variety of machine functions, such as rotary or linear motions, tool positioning and the like. A compressed air supply is maintained accurately at a preselected minimum pressure necessary for a particular operation, by a digitally pulsed air flow control system. Air flow and pressure to the associated actuating mechanisms is also controlled by a digital dithering technique using individual sharp pulses of air, each of which instantly breaks the static friction of the mechanism and causes a discrete precise increment of movement, with rapid consecutive pulses providing continuous motion. The direction, amount, acceleration and speed of travel are controlled by varying the pulse width and rate of air flow and pressure as necessary and for efficiency in air consumption. The system is computer controlled and is readily adaptable to numerically controlled machines, industrial robots and the like.

摘要： A valve actuator control device adapted to control the position of a valve actuator by means of solenoid valves, in which if the actuator position deviates from a desired position, but remains within a predetermined distance from said desired position, the control device is adapted to only return the actuator to the desired position after a delay period, thereby to increase the life span of said solenoid valves.
