Comparison of multi-objective optimization methods for PI controllers tuning

In this work, an analysis of multi-objective optimization methods for PI controllers tuning is presented using the Pareto front concept. A new multi-objective method is proposed to find an evenly spaced Pareto frontier which, at the same time, gives the user an idea of the degradation of one of the objective functions. The results are analyzed from a control theory perspective, which include the comparison with classical PI tuning methods.
