In this paper, a PID controller is designed and constructed to control the output pressure of needle valve in the hydraulic circuit. The valve is controlled by the servo motor which has connected to ...

PID control is a common technique for regulating the temperature, pressure, or flow of a process or system. PID stands for proportional, integral, and derivative, which are the three terms that ...

A LabVIEW program is developed to simulate the working of a pressure regulating valve. The controller is based on PID algorithm to enhance the working of the valve. Published in: 2016 IEEE Annual ...

1. Ratio of ωN to FoA is 2:1, 10 Hz to 5 Hz. Note the RMSE value and velocity oscillation. Figure 2 shows the same motion profile, but with a ratio of FoA to ω N of exactly 4:1, resulting in ...

PID Control: The PID controller uses proportional, integral, and derivative terms to compute the control signal. The controller parameters are tuned to achieve the desired performance in terms of ...

However, a secondary flow loop may cause the PID output response to be slower than desired for gas and liquid pressure control. Here the PID output should go directly to a fast valve (booster on the ...

The controller is suitable for either two- or three-way control valve applications. Standard features of the controller include a wall-mounted NEMA 1 enclosure, temperature inputs/readouts, adjustable ...
