The control of longitudinal waves in a rod having material damping governed by the Voigt model is considered. Wave-mode coordinate methods are used to derive a relation between the force at a general point in the rod and the force applied to one end of the rod. The force relation includes the effects of a single-input single-output controller which prevents the incoming waves from reaching the other...
In several control systems applications, it is important to know how "distant" is the given nominal controllable system from an uncontrollable one. In this note we obtain a simple characterization of the measure of the distance and based on the characterization, obtain the bounds on the perturbations in the state and input matrices that will make a controllable system uncontrollable.
In [16] it is shown that the spectrum of a linear time-invariant multivariable system, using decentralized linear time-invariant controllers, can only be assigned to a symmetric set of complex numbers that include the decentralized fixed modes (DFM). This is of fundamental importance to the decentralized stabilization problem. It is to be noted however, that if a system is unstable and if the unstable...
