To select the best tool for your application, see Choosing a PID Controller Design Tool. As the SERIES PID controller has derivative and integral parts in series, it is sometimes possible to have multiple options or no options when converting to this algorithm (if the derivative term is 0, there is a unique solution). The first justification is that PID controller is by far the most widely used control algorithm in the process industry, and that improvements in tuning of PID controllers will have a significant practical impact. I generally assume P in PID for flow control as 0. The graphs below illustrate the principle. The appendices also offer an insight and understanding that are useful beyond the tuning of controllers. Those are continuous cycling method and damped oscillation method. The PID control scheme is named after its three correcting terms, whose sum constitutes the manipulated variable (MV). THREE TERM (PID) CONTROL The following is a stand alone tutorial to explain the meaning of P.
