Technical Examples

In the present invention, a Smith predictor enhanced PID controller, SP-PID, is proposed. A tuning parameter Ksp is devised and the SP-PID controller would be gradually transformed from a PID controller to a Smith predictor as Ksp changes from 0 to 1. Properties of the SP-PID are explored and the design procedure is given to ensure a certain degree of robustness. Simulation results clearly indicate that the SP-PID takes advantage of the SP when small modeling error is encountered and it is gradually detuned to a PID controller, a user-friendly controller, when the model quality degrades. Moreover, the controller and its design procedure can be implemented in current process control computers with virtually no extra hardware cost.
