Gain scheduling PID is a linear controller and problems may occur because many production processes as flow and temperature are nonlinear. This nonlinear behaviour becomes a problem when the process moves from one operation point to another. Then the controller tuned to a fixed operation point may respond too fast or too slowly. If the
