Abstract
Model reduction and tuning rules given in the SIMC (Simple Internal Model Control) method are very effective in tuning PI controllers. For some processes with large lead elements, control performances by the SIMC method are somewhat oscillatory or sluggish. To mitigate such drawbacks, additional tuning rules based on the second order plus time delay model with lead term are proposed. Improvements for certain types of models are critical. For such processes, besides the SIMC tuning rule, no PI controller tuning rules that are analytic and given in terms of process parameters are not available. Since the proposed tuning rules are very simple, they can be used in the field, effectively complementing the SIMC method.
