โœฆ Synopsis


Two basic series expansions are considered which provide the forced response (zero initial conditions) and the free response (zero input) of nonlinear analytic systems. The whole response is expressed aa the cum of a "jree respome" and of a term which my be computed directly from a "forced response". Furthermore, it is show-n that both the kernels appearing in the series expansion of this term and the kernels characterizing the free response are directly related to the kernels of the forced response starting from zero initial conditions.

It is shown how a frequency domain criterion can be used to obtain meaningful bounds on the responses of nonlinearfeedbac7~ systems. If the system is rlisturbed by a known input or ?zonsm~ initial condition from its state of equilibrium, bounds are obtained on ouer shoot and settling time as the sys
