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 th
e problem and its consequences on industrial applications are described. Th
en a framework for studying the effects of set-point weighting in ISA-PID c
ontrollers is introduced. Finally, a method and the corresponding procedure
for tuning the weights are developed. Simulation examples showing the effe
ctiveness of the proposed approach are also presented.
