Design of Smith internal model controller with relay feedback

This paper presents a new method on designing Smith predictor based on the internal model control(IMC) theory. This method is capable in solving the mismatch problem by identifying the model parameters of process objectives through relay-based feedback and adopting the self-adaptive theory. The experimental result indicates that this simple and easily utilized algorithm can achieve outstanding results in the control systems with large time-delay.
