WebTHE SMITH PREDICTOR A simple algorithm for control processes affected by dead time is the one proposed by Hägglund (named Predictor-PI) 2 and based on the idea of decreasing the manipulated variable by an amount equal to all that was computed in the last τ seconds. WebIt is known that the Smith predictor (Smith 1957, 1959) is a simple and often used strategy for large time-delay compensation. The principle of the Smith predictor is to construct both of a model with time-delay and a model free of time-delay as well. It is assumed that the models that are used to describe the process are precise enough.

Web28 Jul 2024 · The Smith predictor was proposed in the 1950s to compensate for the long dead time of a process and significantly improve the control performance. Time delays are inherent in various chemical processes. However, a dead time greater than the time constant of a process can severely deteriorate the PID control performance.
