The unique characteristic of a repetitive process is a series of sweeps or passes through a set of dynamics defined over a finite duration known as the pass length. At the end of each pass, the process is reset and the next time through the output, or pass profile, produced on the previous pass acts as a forcing function on, an hence contributes to, the dynamics of the new pass profile. They are hence a class of systems with information propagation in two independent directions where here the dynamics over the finite pass length are described by a matrix linear differential equation and that from pass to pass has a discrete updating structure. This means that filtering/estimation theory/algorithms for, in particular, 2D discrete linear systems is not applicable. In this paper we solve a general filtering problem with a view toward use in the many applications where such action will be required.
Theory, computation and applications define the evolution of the field of control. This premise is first illustrated with some historical examples and then with the emerging area of hybrid systems, which can be viewed...

Nonlinear control systems are more difficult to handle than linear, since the associativity is not valid. Laplace transforms and transfer functions, which form a symbolic computation for linear systems, are, therefore, disabled. A modern development of nonlinear control systems is thus related mainly to the systematic use of differential algebraic methods. However, such methods allow us to introduce similar symbolic computation also for nonlinear systems. To provide a basis for such a symbolic computation the theory of non-commutative polynomials over the field of meromorphic functions is introduced. In that respect, differential operators, which act on one-forms, play a key role. They form the left skew polynomial ring. Quotients of such polynomials stand for transfer functions of nonlinear systems. In other words, presented paper tries to show that there is no reason to believe well known dogma saying that nonlinear systems have no transfer functions

The aim of this paper is to give an overview about some ideas that have been introduced in past few years to the course Automatic control Fundamentals at FCFT STU. These involve heavy use of information technologies and reduction of repetitive pedagogic work using e-learning techniques for the course with a large number of students. The paper discusses reasons for this change as well as concrete technologies in question.

The problem of design of a controller for a large-scale system is studied. The design objective is to achieve behavior comparable with the standard controller that is LQ optimal. On the other hand the amount of interconnections between subsystems should be kept as small as possible. This is guaranteed by solving of an optimization problem where the number of interconnections is minimized while the difference in the values of the cost functional for the standard and decentralized controller is a constraint. To find the value of the cost of the decentralized control in presence of interconnections one can use linear matrix inequalities.
