This project aims to build a set of wind pressure control experiment using a PID controller with the major hardware components, namely: compressor valves, noi Li solutions. Opening control system circuit of solenoid valve. Gas tank. Pressure sensor circuit interfaces and control the PID through Lab view by such systems will produce solar wind pressure drop into League นอย์ VAO (input) Which serves to close the open access of the wind by using electrical control (gas tank) when the wind into the gas tank, pressure to the pressure sensor. The sensors will control the operation of the interface circuit to circuit interface works by going to the control circuit to control both the solution Li นอย์ to speak, and when there is excess pressure in the gas tank, so to speak, wind Li นอย์ acts to dribble out of the gas tank. Then in the section software, the system will begin by reading the data from the sensors and pressure value measured at the input to the DAQ. Access to the PID control, which has a first choice with 2 is processed automatically, the program automatically calculates the average minimum error of the Kp, the second is Kd, Ki work by hand instead, automation. The performance test experiment set set point adjustments begin at 10 Psi-50 Psi, which is the result of experiments it was found that at 50 Psi. An older brother was born over a specific set of possible tightness tanoi this trial. The first term entered Kp by Ki and Kd constant Gain, higher values will make the work faster, but the response is occurring over the same tightness tamak! The second input term given Ki Kp and Kd constant can also cause over Shu. The system is a higher Order and may make the system is the result of unsolicited responses. The third input Kd term set to Ki and Kp constant. This term can be reduced as a result of the response over Shu. PID are clear at 50 Psi set point, because the graph of PID is minimal Overshoot occurs.
