This paper is in three parts. The first deals with the algebraic and topological structure of spaces of rational transfer function linear systems--ARMAX systems, as they have been called. This ...

Linear actuators and oscillating systems constitute a vibrant area of research that bridges concepts in electromagnetism, mechanics and control engineering.

The object of this paper is to develop a unifying framework for the functional analytic representation of infinite dimensional linear systems with unbounded input and output operators. On the basis of ...

Rack-and-pinion sets deliver precise motion over unlimited lengths without the complexity of motors and ball screws.
