Autotuning methods are typically conceived as procedures; thus need simulating as digital blocks. However; when no autotuning is in progress; it is far more efficient to represent the tuned controller as a continuous-time system; to exploit variable-step integration. This manuscript presents the first nucleus of a Modelica library of autotuning controllers; where the problem just mentioned is tackled explicitly. The focus is here restricted to the PI structure; but the presented ideas are general.
