This paper deals with the orders of input/output equations satissed by nonlinear systems. Such equations represent diierential (or diierence, in the discrete-time case) relations between high-order derivatives (or shifts, respectively) of input and output signals. It is shown that, under analyticity assumptions, there cannot exist equations of order less than the minimal dimension of any observable realization; this generalizes the known situation in the classical linear case. The results… CONTINUE READING
