— This paper investigates string stability issues in homogeneous strings of strictly proper feedback control systems. We consider initial condition problems with unidirectional nearest neighbour communications, using only linear systems with two integrators in the loop. We define string stability as a type of stability that is uniform with respect to the(More)

We show under which conditions the induced L2-norm of the disturbance to error transfer function is bounded independently of the(More)

In this note we consider the problem of determining necessary and sufficient conditions for the existence of a common quadratic Lya-punov function for a pair of stable linear time-invariant systems whose system matrices are of the form A, A − gh T , and where one of the matrices is singular. We then apply this result in a study of a feedback system with a(More)
The basic theory of supervisory control of discrete-event systems is extended with the notion of <i>templates</i>, which simplifies the modeling of controllers since one can work with conceptual designs. In this work, software which provides support for the new design approach is presented along with its application to a robotic testbed.
