Proportional Integral Derivative (PID) control automatically adjusts a control output based on the difference between a set point (SP) and a measured process variable (PV). The value of the controller output `u(t)` is transferred as the system input.

At 11:00 a.m. the operator decides to switch the loop back in Automatic mode. At that time the SP = 280°F and the PV = 220°F. Maria João Mortágua Rodrigues PID Control of Water in a tank 8 2.2 PID Controller Feedback loops have been controlling continuous processes since 1700’s.

The operator decides to manually decrease the control valve position from 40% to 30%. The PV, after several minutes, settles out at 220°F.

The third column lists the variable values for the Override PID. The grayed out variables (Process Variable and Output) are read only. They monitor those variables and cannot be “set” by the operator. The three “scales” (PV, SP and Output) provide a live, visual indication of those three variables. In theory, a controller can be used to control any process that has a measurable output (PV), a known ideal value for that output (SP), and an input to the process (MV) that will affect the relevant PV. PID = Proportional, Integral, Derivative algorithm.

[2] Today, there are several more controllers, but most of all derivates from the PID controller. “The PID controller is by far the most common control algorithm. Most feedback loops are PID控制器可以追溯到1890年代的 調速器 ( 英語 : Governor (device) ) 設計 。 PID控制器是在船舶自動操作系統中漸漸發展。1911年 Elmer Sperry ( 英語 : Elmer Sperry ) 開發的控制器是最早期PID型控制器的其中之一 ,而第一個發表PID控制器理論分析論文的是俄裔美國工程師 尼古拉斯·米諾爾斯基 ( 英語 S7-1215, TIA Portal V11 SP2 Upd5I have an application where I need to be able to vary the Gain on a PID controller, well actually it is just a PI controller.

In this configuration page, there is a real time trend chart to show the values changing of SV, PV and MV. It is very helpful for user to monitor and diagnose the PID control situation.

The value of the controller output `u(t)` is transferred as the system input. Pv should change with MV; when MV is already reach 100% PV should have reach the desired set point (SP), if not then the process is lack in efficiency. Then, for this experiment with full range avaibility, one simply must plot a graph of MV against PV to observe the graph where you can see a straight line with no curves. output (PV), a known ideal value for that output (SP) and input to the process (MV) that will effect the relevant PC. Controllers are used in the industry to regulate temperature, pressure, flow rate, chemical composition, speed and practically every other variable for which a measurement exists. Automobile cruise control is an Recall that the purpose of integral action in a PID controller is to eliminate offset between process variable and setpoint by calculating the error-time product (how far PV deviates from SP, and for how long). The PID controller looks at the setpoint and compares it with the actual value of the Process Variable (PV).
