Abstract :
We propose a connection between the state-space realization and dasiaobserver-likepsila property of a nonlinear feedback system, consisting of an linear time-invariant (LTI) plant and a nonlinear controller by utilizing dasiakernel representationpsila of dynamical systems. This connection is advanced by noticing that the kernel representation shares many properties with and is indeed a generalization of left fractional representations for nonlinear systems.
