This paper proposes a design method for continuous‐time VRFT (Virtual Reference Feedback Tuning) for I‐PD (Integral‐Proportional, Differential) gain tuning using closed‐loop step response data. The I‐PD controllers can avoid an abrupt change of manipulated variables, and have been widely used for industrial process control. The present work derives an optimal prefilter condition, and a design procedure of an optimal prefilter. The efficiency of the proposed method is assured using a numerical example and a helicopter attitude control experimental result.
