This article draws its motivation from classical model‐based controller design methods, such as Direct Synthesis (DS) and Internal Model Control (IMC) methods, and develops a model‐based PI‐like control scheme for stable systems. The proposed control scheme has been realized in a reset configuration. Furthermore, the control scheme has a tuning parameter, and its control action resembles a PI‐like controller. The proposed scheme shows improved performance as compared to that of IMC, Skogestad‐IMC‐PI, and Skogestad‐IMC‐PID control schemes. In addition, an automated approach to designing this scheme is proposed. The efficacy of the proposed control scheme is demonstrated via experimental evaluation on a computer‐interfaced pilot‐scale two‐tank system.
