The electric drives based on DC collector motors, which orient the solar cells perpendicular to the normal of the incident solar rays, are extremely widespread in solar engineering (along with stepper motors) due to a wide range of speed control, simple controllability and relatively high energy efficiency. To extract the maximum amount of energy, it is necessary to carry out a qualitative control of the electric drive. Modeling is an important stage in the practical design and application of solar control systems. Existing approaches, as a rule, ignore some important nonlinear properties of the electric drive. These nonlinearities can play a very important role in the management of solar actuators, which operate under different conditions and require high accuracy of operation, therefore, necessitate a non-linear approach in modeling. In other words, to ensure effective control in the design of control, nonlinearities must be taken into account. The purpose of the article is to synthesize a complex model of a servomotor DC drive, taking into account nonlinear properties.
