P.I.D. control described in 12 interactive screens of text, graphics, and animation.  P.I.D. (Proportional, Integral, Derivative) control is the state-of-the-art way to control continuous processes such as temperature, level, flow, or pressure. The program first explains the basics of P.I.D. control and draws proportional, integral, and derivative outputs as you vary an error signal.  Then the program allows you to actually "tune" an example furnace controller and liquid level controller by adjusting Gain, Reset, and Rate for the best control.
