Abstract: In the paper, an add-on controller design based on disturbance observer for a class of single-input single-output (SISO) linear systems is proposed in Hoo framework. Motivated by the previous research of reinterpretation of disturbance observer as an add-on controller, the disturbance observer is designed to minimize reference tracking error which is the ultimate objective of every control system by minimizing disturbance estimation error. Since the disturbance estimation error may amplify reference tracking …
