Abstract :
A notion of q-integral (qI) observers for multiple-input single output linear systems is introduced. Then the theory is extended to nonlinear systems with single output. We show that the q-integral observer guarantees robustness against both measurement errors and unmodeled dynamics. An example is given to show the efficacy of the proposed robust observers.
