|Abstract:||Performance of internal model control (IMC), which is affected by the inevitable errors in the model used, can be improved by augmented IMC (AuIMC) having an additional feedback of process/model mismatch through a suitable gain. This paper presents a detailed study on real-time control of an open-loop stable single-input-single-output (SISO) nonlinear system by AuIMC. The AuIMC structure is first analyzed theoretically to show its robustness and performance characteristics, followed by its experimental evaluation on pH control of a neutralization process. The experimental results show that significantly improved control is obtained by the AuIMC compared to the standard IMC. (C) 2000 Elsevier Science Ltd. All rights reserved.|
