Abstract

This paper presents a PID based control with low-order Disturbance Feedback Control (DFC). DFC is a technique to improve the existing control systems with an extra feedback which attenuates disturbances and model errors. This work analyzes Robust Performance (RP), which is the measurement of the robustness and performance of the DFC. A simple grid-based search algorithm is proposed to design disturbance feedback such that DFC can achieve RP for the control system with model uncertainties. Numerical examples show that better performance can be achieved with DFC in comparison with an existing PI controller.
