The document summarizes a student project on web-based control of a pressure loop apparatus using LabVIEW. The project involved designing a closed-loop feedback control system using proportional, integral and derivative (PID) control to regulate air pressure. A virtual laboratory system was created using G-Web Server in LabVIEW to allow remote web-based control and monitoring of the pressure loop. The system could enable applications such as virtual laboratories for distance learning or web-based supervisory control and data acquisition in industry.

- 8. P, PI and PID Control Proportional Response: Difference between the set point and the process variable . Increasing the proportional gain (K c ) will increase the speed of the control system response. Integral Response: Sums the error term over time. Effect is to drive the Steady-State error to zero. Derivative Response: Causes the output to decrease if the process variable is increasing rapidly. Increasing the derivative time (T d ) parameter will cause the control system to react more strongly to changes in the error term and will increase the speed of the overall control system response.
