Links and abstracts
1.1. Classification of objects and controls systems and their models
Classification so boring occupation, as far as and useful. Good classification allows to survey a subject or its section as a whole and determines the basic concepts and a nomenclature.
- 1.1.1. Classification of models physical and engineering systems and devices. 12.11.2002
- 1.1.2. Classification of standard links on the basis of properties of linear systems. 20.02.2003
- 1.1.3. Dynamic objects. What is it such and what for, why and as they are presented by differential equations. 3.01.2008
1.2. Mathematical description of objects and controls systems
The mathematical description of systems and objects is their analytical model. Such model, depending on entirety of its correspondence to the hardware system or the object, allows to research their properties in a general view. The analytical model can form the basis for construction of objective models of systems units and systems as a whole.

- 1.2.5. About calculation and plotting of frequency characteristics of linear systems in Mathcad
Simple, but effective methods of compact plotting of the frequency characteristics, essentially speeding up run time are observed.
Naturally-logarithmic form of representation of Mihajlov's and Nyquist's hodographs is offered, allowing compactly to present the hodograph in major frequency band at saving of correct mapping of arguments.

1.3.2. Quality
Quality of the automatic control system is characterised by its ability to solve it's tasks: to execute stabilising and tracing.
