Analysis of integrated starter-generator operation in the starter mode on a mathematical model

New consumer requirements to modern cars have resulted in developing an integrated starter-generator. This multifunctional and multiconnected system is of great interest for commercial application. The integration of the internal combustion engine, the starter and the generator into a single power unit allows one to implement qualitatively a new concept of a car power unit with a substantial improvement of its ecological parameters. The results of this integrated starter-generator modelling in the starter mode in all ranges of speeds and initial conditions are given in this paper. The realization of the proposed control system is described on a mathematical model. The control algorithm has been verified by using the "Matlab-Simulink" software.
