✦ Synopsis

The bounded-input bounded-output stability of feedback control systems with time-varying gain is studied, and both continuous and sampled-data feedback systems are considered. It is shown that if the total gain deviation from a constant is finite, and if the feedback system with that constant gain is stable, then the output of the time-varying feedback system due to any bounded input is bounded; furthermore, the response of the time-varying system tends to that of the constant gain system. Similar results, somewhat weaker, are obtained far the time-varying sampled-data feedback system.

A su~cient condition for absolute stability in the bounded-input-bounded-output sense for a class of nonlinear sampled-data systems is obtained. The stability theorem yields a Popov-type frequency domain test on the linear plant. The obtained criterion is identical to the criterion that establishes
