1.4. Synthesis of the automatic control system (ACS)
The assemblage automatic control system synthesis and optimisation methods is known testifies that the universal methods are not discovered yet and projection of the automatic control system in many respects concerns to field of engineering art.

1.5. Nonlinear systems
Any system or object in process of increasing of magnitude of effects on them become nonlinear. The stringent theory of nonlinear systems is difficult enough for engineering applications, therefore engineers-designers are compelled to use with the approximated analytical methods. Object-oriented nonlinear systems simulation programs can essential to simplify the analysis. For example, Visual Solution corporation motto the following: "If the task nonlinear there is a visual solution!"

In many cases it is necessary to ensure control of several controlled variables of the object, its output variables, by action on some its inputs, i.e. modifications of controlling variables, plus to that should be considered also some disturbances. The control singularity such, difficult enough object in exposition, consists that can happen that action on one entry leads to a modification not to one, and at once several controlled variables. For example, on some estimates [7-2], in chemical processes of the order of 15 % make doubly linked control systems. We will illustrate singularities of multi-dimensional objects of control with following instances.

The present article purposes is evident consideration of singularities of description of multi-dimensional objects and control of them, allowing to achieve understanding of an essence of case.
Generalisation of state equations on nonlinear multi-dimensional dynamic objects and the control systems having extention in space and units of transport delay is conducted. Generalisation is executed by incorporation of delay links, along with integrators, in a structure of the elementary dynamic, i.e. such which output variables are treated as self-maintained state variables.
