8 CONCLUSION
The state-space methods presented in this chapter offer a unifying framework for the dynamic
analysis and control of a variety of systems. The primary emphasis in these methods on
linear time-invariant systems is a reflection of the state of the literature on the subject and
the practice of the art. Results for linear time-varying systems have been given in some of
the standard texts 2–4 referred to. The application of state-space methods to nonlinear system
analysis and control is treated at some length by Hedrick and Paynter. 21
Distributed-parameter systems are examples of systems with infinite-dimensional states.
Application of state-space methods to these systems has been described by Tzafestas et al. 22
Time-delayed systems are also examples of systems with infinite-dimensional states. The
analysis and control of such systems and of many of the other types of systems referred to
in this section remains a subject of current research. For current research results in these
areas, the reader is referred to journals such as the ASME Journal of Dynamic Systems,
Measurements and Controls; IEEE Transactions on Automatic Control; AIAA Journal of
Guidance, Control and Dynamics; SIAM Journal on Control; and Automatica, the Journal
of the International Federation of Automatic Control.
