MATHEMATICAL MODEL OF RESISTOR EFFECT ON THE SYNCHRONIZATION SYSTEMS

Abstract: In this paper, a new mathematical model is built using the electrical working shaft as a speed synchronization system with additional resistor in the common rotor circuit. Effective role of additional resistor on the synchronous capability and recovery time of the system is studied by using simple overhead crane. The calculated and experimental results show that the relationship between the necessary for synchronization additional resistor and the system’s synchronous capability depends basically on the position of crane hoist (load distribution on the shafts). It is found also that increasing the additional resistor value gives a great capability of synchronization. Simultaneously proportional lead to a drop in the system efficiency. To overcome this drawback, a controller block is added to determine the optimal value of the additional resistor according to the hoist position or to the difference of loads on the motors shafts. |
Keywords and phrases: mathematical model, additional resistor, synchronous capability. |
