Abstract
RESEARCH OF THE DC MOTOR ON THE IMITATION MODEL
V. Miroshnyk, Y. Tsitsyurskiy
In the agriculture of Ukraine, the electric drive accounts for the majority of electricity consumption. His research as an object of control on simulation models will reduce costs and increase the efficiency of creating automatic control systems for electric drives.
The aim of the research is to create an imitation model of a DC motor through the speed control channel to create an automation system.
Based on the well-known mathematical model of a DC electric motor as a control object, a parametric circuit and a simulation model have been developed in the Simulink MATLAB environment.
With its help, the effect of control parameters (voltage U and perturbation Mc) on the control parameter (the speed of the motor shaft) was investigated. For the electric motor that is being investigated, the vector of generalized coordinates, the control scalar, the perturbation scalar are defined, a program is developed in the MATLAB environment for determining the transfer function of the electric motor. An example of calculation of the transfer function is given. The resulting simulation model enables students to develop more efficient DC motor control algorithms.
