- This paper is concerned with the design of the closed-loop control system, in order to take into account the system performance to load-disturbance and to set-point changes and its robustness to variation of the controlled process characteristics. The aim is to achieve a good balance between the multiple trade-offs. The proposed approach is complementary to the work presented by Arrieta and Vilanova (2011, 2012). Here, it is provided a PID design that allowing some degradation in the system's combined performance, achieves an increase in the robustness.
