    Opis:
    In the paper the influence of broken rotor bars to the properties of vector controlled induction motor drive system was checked. Characteristic frequency was shown. The rotor fault detector based on the neural network was described and tested in simulation. Proposed algorithm was applied in the Direct Field Oriented Control Structure of Induction Motor. Control structure was tested and checked during different drive operation. Simulation results were performed in Matlab Simulink software.

    Maximum Torque Control
    Opis:
    Maximum Torque Control (MTC) is a new method applied for control of induction motor drives. The drive is controlled by dc voltage supplying a converter in the range below nominal speed and by a field that weakens for a speed range above the nominal speed. As a consequence, the control is quite similar to the control of a classical separately excited dc motor. This control method could be explained as a kind of simplification of Direct Torque Control (DTC), because the switching scheme is the same as for the DTC, but the variable responsible for a torque control is constantly set for “torque increase”. This kind of control of induction motor drive is simpler than DTC because torque values need not be estimated. The proposed control method offers very good performance for 3-phase induction motors and requires smaller switching frequency in comparison to DTC and Field Oriented Control (FOC). The application of the control is widely demonstrated for a 3-phase 315 kW, 6 kV motor drive by use of computer simulation.

    In this paper, an analysis of the influence of the stator winding resistance on the field-weakening operation of the induction motor drive based on the Direct Rotor Flux Oriented Control (DRFOC) is presented. Two scenarions of the optimal field-weakening algorithm (with and without stator winding resistance taken into account) have been compared and verified through simulation and experiment, under different operation conditions of the DRFOC drive system with 3 [kW] induction motor.

    Opis:
    Analytical research methods to determine the power characteristics of generator sets with vector control in an asynchronous squirrel-cage machine were developed and used to calculate the energy characteristics of generator sets with the field-oriented control (FOC) and direct torque control (DTC). The analytical calculations showed that a generator set with direct torque control had slightly better energy characteristics. Confirmation of the analytical calculation results was carried out using simulation models developed in the MATLAB-Simulink package with an environment Simscape Power System.
