✦ Synopsis

Abstract

A stability condition is developed for multivariable, nonlinear feedback systems. The method is based on a modified sector condition and is combined with a polynomial expansion of the nonlinear system to create viable approximations that can be exploited within the sector bound setting. An example demonstrates the utility of the method in defining stable operating regimes for chemical processes.

The effect of unmodeled fast actuator dynamics on the output feedback stabilization of feedback-linearizable systems is studied. It is shown that if the actuator dynamics are suBiciently fast, the output feedback controller will stabilize the origin of the actual system. Moreover, it is shown that t

We consider a multiple-input multiple-output feedback system consisting of a linear time-invariant subsystem and a memoryless time-invariant nonlinearity. The linear subsystem is represented by its impulse response which includes a unit step, i.e. an integrator. The nonlinearity is not required to b
