The purpose of this research is to analyze frequency convertors in view of its utilization in automatic control. It concerns mainly application of frequency convertors for actuator mechanism and servomechanism with adjustable speeds and with adjustable torsion moment. It is presumed to analyze mainly dynamics properties of control loops and frequency convertors utilization design in relation to advanced techniques of automation control.

Artificial intelligence methods belong among modern methods for optimization of system and process control. These methods are especially suitable to apply to problems that are very difficult to solve by using classical mathematical methods or where the application of deterministic computation methods would require unacceptable simplification of the problem. Obtaining the optimal data by means of modern methods and algorithms of artificial intelligence is an important task for solving problems of face localization and recognition in the area of system and process control. Approaches used by a graduant while solving the given task are as follows: Analysis of face localization methods, analysis of neural networks and genetic algorithms for face recognition.

Discretization is used for analysis and synthesis the continuous-time control systems. But is possible their use for solutions of continuous-time systems and for simulation continuous-time systems. It is new aspect of the analysis the continuous-time control systems. One of the simplest ways of discretizing or approximating a continuous-time plant is numerical approximation of differential equations. Difference equations can be obtained by discretizing differential equations. The other way of discretization is discretization by z transformation of transfer function G(s). In this suggest work is solution by Euler's method and bilinear method of this transformation and a method when the derivative term is simply replaced by a first-order difference expression and the integral by a sum. A new part of work will be solutions of unit step response and impulse response of continuous-time systems by discrete methods. It will contain an algorithm for their calculation.
