The electrical drives consume about 70 % of total generated energy in the world. The induction drive is a most widely used in various industries; however it has well-known disadvantages such as a comparatively low power factor. The electrical drive based on switched inductor motor with independent electromagnetic excitation as a good alternative to the induction drive because of various advantages related to the energy efficiency. At the same time this type of drive is sensitive for the coordinating and parametric disturbances which may affect energy efficiency and quality of control in various technological processes. This paper proposes the method of the development of control laws based on an idea of the reversibility of the Lyapunov direct method for the stability analysis, and using the instantaneous value of energy as the predetermined Lyapunov function. This will ensure effective operation with a lesser sensitivity to variations of the motor’s parameters, as well as the simplicity of realization of control system. Modelling of the proposed electrical drive is confirmed by a good control performance and the workability of the system. Results of this study will support further application of the switched inductor electrical drive in the industrial technologies.
