Abstract :
The existence of a fixed internal dynamics, inherent to the noninteraction requirement, is identified. When unstable, this represents an obstruction to the achievement of noninteracting control with stability, by means of static state-feedback. Remarkably, whenever one leaves the class of linear systems, this obstruction cannot, in general, be removed by dynamic state-feedback.<>
