This paper deals with the study of electromechanical systems.

According to the studies for selected electromechanical system (Fig.1) speed regulator with polynomial regulator of tension is the most appropriate type of the system, because its quality indicators meet all the criteria.

Figure 2. The dependence of the tension from time to time

For a system with speed regulator it is necessary to make a synthesis of polynomial regulator (Fig. 3).

Figure 3. Block diagram of a polynomial regulator

The transfer function for tension has the following form:

where D (s) is the desired characteristic polynomial.

Let us define the geometric mean root Ω0 of desired characteristic polynomial:

Software Satellite is used to determine polynomials regulator. Thus, we obtain the following polynomial regulator:

Figure 5.Dependence of the tension of electromechanical system with speed regulator with polynomial regulator of tension

Thus, quality analysis of electromechanical system with speed regulator with polynomial regulator of tension shows:

1. Overshoot:

2. Speed recovery time: Т_R= с.

3. Transition process time: Т_TP=0.15 с.

So, this work can be interesting for students whose major is electro mechanics and electronics.
