Method for optimising set-point weights in ISA-PID autotuners

The aim of the paper is to address the problem of optimising the set-point weights of an ISA-PID controller automatically. First, the importance of the problem and its consequences on industrial applications are described. Then a framework for studying the effects of set-point weighting in ISA-PID controllers is introduced. Finally, a method and the corresponding procedure for tuning the weights are developed. Simulation examples showing the effectiveness of the proposed approach are also presented
