2. Pressure regulator - Wikipedia

   en.wikipedia.org/wiki/Pressure_regulator

   Diagram symbols for pressure reduction and back pressure regulators. The conceptual difference is mainly in which side the feedback is taken from. A pressure regulator is a valve that controls the pressure of a fluid to a desired value, using negative feedback from the controlled pressure. Regulators are used for gases and liquids, and can be ...

3. Gas cylinder - Wikipedia

   en.wikipedia.org/wiki/Gas_cylinder

   The regulator is adjusted to control the downstream pressure, which will limit the maximum flow of gas out of the cylinder at the pressure shown by the downstream gauge. For some purposes, such as shielding gas for arc welding, the regulator will also have a flowmeter on the downstream side.

4. Regulator (automatic control) - Wikipedia

   en.wikipedia.org/wiki/Regulator_(automatic_control)

   Examples are a voltage regulator (which can be a transformer whose voltage ratio of transformation can be adjusted, or an electronic circuit that produces a defined voltage), a pressure regulator, such as a diving regulator, which maintains its output at a fixed pressure lower than its input, and a fuel regulator (which controls the supply of ...

5. Control valve - Wikipedia

   en.wikipedia.org/wiki/Control_valve

   A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. [1] This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level.

6. Linear–quadratic regulator - Wikipedia

   en.wikipedia.org/wiki/Linear–quadratic_regulator

   One of the main results in the theory is that the solution is provided by the linear–quadratic regulator (LQR), a feedback controller whose equations are given below. LQR controllers possess inherent robustness with guaranteed gain and phase margin , [ 1 ] and they also are part of the solution to the LQG (linear–quadratic–Gaussian) problem .

7. Proportional–integral–derivative controller - Wikipedia

   en.wikipedia.org/wiki/Proportional–integral...

   He explored the mathematical basis for control stability, and progressed a good way towards a solution, but made an appeal for mathematicians to examine the problem. [ 6 ] [ 5 ] The problem was examined further in 1874 by Edward Routh , Charles Sturm , and in 1895, Adolf Hurwitz , all of whom contributed to the establishment of control ...
