Abstract :
In this paper, a new tuning rule is proposed for PI controllers for first-order plants with time delay. The novelty of this tuning is that it takes into account multiobjective optimizations methods with a closed-loop robustness criterion. When compared with other classical tuning rules, it was found that the proposed rules give better results for both input and output disturbances.
