TLDR
In this article, a method for controlling a dome-operated pressure regulator is described and a proportional control valve is used to control the pressure on at the dome side of the pressure regulator.Abstract:
A method for controlling a dome-operated pressure regulator is disclosed. The pressure at a dome side of the pressure regulator is measured. The operation of the pressure regulator is controlled based upon at least a received command signal and the measurement. A proportional control valve may be used to control the pressure on at the dome side of the pressure regulator. A controller and a system are also disclosed.read more

Controller gain scheduling for mass flow controllers
TL;DR: In this paper, a mass flow controller with a feedback controller gain is described. But the feedback controller is not considered in this paper, instead, it is assumed that the closed loop transfer function of the feedback system remains substantially constant regardless of operating conditions so as to have a consistent control performance at different operation conditions from the calibration condition.

Automatic pressure regulator for flow rate regulator
TL;DR: In this paper, an automatic pressure regulator for a flow regulator was proposed, where overshoot is prevented from occurring in flow rate on the output side when the output flow rate of the flow regulator is altered or the type of gas to flow is altered.

Kieran Mcmahon,Eamonn O'halloran +1 more
TL;DR: In this article, a thermal energy machining (TEM) machine gas handling system is described, in which the improvement is a fluid-controlled pressure regulation subsystem for controlling the dispensing of a TEM process gas via the regulation of the pressure of the process gas.
Patent
Valve positioner having bypass component and control valve comprised thereof
TL;DR: In this article, the valve positioner incorporates a by-pass component, which can utilize control input signals (e.g., a 4-20 mA signal) to energize one or more components to cause the control valve to modulate fluid flow without the digital microprocessor and/or related components.

Valve positioner with pressure feedback, dynamic correction and diagnostics
TL;DR: In this paper, a valve positioner receives a setpoint from a master and provides a control pressure to a valve actuator for controlling a valve, and a control circuit in the positioner uses both the sensed pressure and position to provide a command output to a pneumatic section which produces the control pressure.

Fluid flow control system, fluid delivery and control system for a fluid delivery line, and method for controlling pressure oscillations within fluid of a fluid delivery line
TL;DR: A fluid delivery and control system for a fluid delivery line having elastic components is described in this paper. But the system is not suitable for the use of computer program code logic (CCL).
Patent
Disk drive pulse width modulating a voice coil motor using model reference current feedback
TL;DR: In this paper, a disk drive is disclosed comprising a voice coil motor (VCM) driven in a PWM mode using model reference current feedback, which varies with changes to the plant characteristics, such as the resistance of the voice coil fluctuating with temperature drift.
