Certain control problems in distributed systems

Abstract

The paper consists of several Sections devoted to different facets of the distributed system control.

Section 1 covers control of liquifier feed distribution along the describing line of thin sheet rolling mill rolls in order to optimally control the shape of the roll and the gap disturbed by thermal expansion.

Section 2 deals with active suppression of harmful and generation of useful pressure variations and gas flows in long gas pipelines via active control of the external gas source.

Section 3 poses a number of control problems for mobile energy sources acting on distributed plants where transfer processes take place.

Section 4 employs numerical theoretic methods to solve the problem of determining the set of points where a distributed oscillatory system is controllable.

Section 5 introduces within the framework of the finite control theory the notion of fundamental finite control in analogy with fundamental solution of the equations.

Finally, Section 6 describes the application of certain aspects of the flowchart and block theory to distributed systems.
