Induction Motor Starting With DC Link

In this paper, the basic formulas of a three-phase induction motor are extracted and by Park_ Transfer Matrix are converted to dq space, then in m_file MATLAB software, are modeled and simulated. The aforementioned three-phase induction motor using cascade control and by A battery is set up and operated and controlled at different speeds. In the end, different diagrams of three-phase induction motor are presented in different working conditions. After carefully examining of the diagrams of three-phase induction motorو proves the accuracy of the proposed control method and its simulations. performance diagrams show that using the proposed control method, the motor can easily follow the reference speeds in the fastest possible time, which proves the accuracy of the modeling and simulations performed. By controlling the speed of induction motors, application of Direct Current motors in Navy of the Islamic Republic of Iran vessels, which are very expensive to maintain, can be eliminated.
