Abstract

The control problem is formulated in terms of interconnections. The interconnections of linear time-invariant systems are studied from this point of view. Two main results are obtained. Any polynomial can be obtained as the characteristic polynomial of an interconnection with a given plant, provided the plant is not autonomous. Any subsystem of a controllable system can be implemented by means of a singular feedback control law. These ideas are finally applied to the stabilization of a nonlinear system around an operating point.
