Abstract :
This paper presents an efficient numerical method to design PI controllers. The design is based on optimization of the load disturbance rejection, with constraints on the sensitivity and weighting of the set point response. Thus, the formulation of the design problem captures many aspects of industrial control problems. It leads to a nonconvex optimization problem. Efficient ways to solve the problem are presented.
