Title: Nonlinear state space models of the generalized induction electromechanical converter based on a stationary coordinate frame Keywords: Induction motor control, Nonlinear systems, Park and Clark transformations, Electromechanical converter, Three-phase induction machine. Abstract: A mathematical description of the electromechanical energy conversion in induction motors is presented in the paper. The dynamic equations connecting the currents the currents and fluxes in the electrical motors are built by taking the projections of the respective variables in a stationary orthogonal coordinate frame. Those equations are untied with regard to different variables by solving the equations for the derivatives of the respective variables. Orientated nonlinear non-autonomous state space models based on state variables choices stemming from the solutions are created, describing the electromechanical conversion of energy. The structural properties of the proposed nonlinear state space models are analyzed with regard to complexity, observebility, and suitability for nonlinear observers design. The peculiarities of the models are considered from the viewpoint of non-autonomy, boun conditions, stiffness and numerical properties. References (11) References Issue
