Vectorial Control of the speed of an induction motor is an advanced speed Control method, enabling us to Control torque, magnetic flux individually as that of DC motor. This paper pre3sents, the effecting factors dominating on the motor &the primarily vectorial Control, leading to an advanced model of Control in various &arbitrary co- ordinate systems. Finally a biased Field Control method with/&without speed sensors, introduced & simulated.

In the present study, Field Oriented Control of step motor implementation has been analyzed so that it can make a Sensorless Control. Efficiency and Facilities of step motor is more than other types of electromotor. Therefore, the numbers of mechanisms and different types of turning can be made into them. Also Controlling these motors is easier than other available motors. Stepping motor has been designed with Oriented Control in MATLAB software by using a Simulink tool box. In two methods above, current, torque and engine speed have been investigated by and without using Kalman filter. The results showed that using Field Oriented Control can eradicate resonance abnormalities. By using Field Oriented Control, the maximum theoretical engine performance can be achieved.

In this paper, a new Field Oriented Control scheme with maximum torque for permanent magnet hysteresis synchronous (PMHS) motor has been presented. Vector Control method provides significant improvement to the dynamic performance of ac motors but in this method d- axis current is Controlled such as the ratio of motor torque to motor current is a maximum, then the dynamic performance will be very fast. Furthermore, d and q axis currents are limited such as stator winding currents remain in the allowed range. Feedback method is used for the decoupling the torque-current component from the flux current component so these two components can be independently Controlled. Simulation results for the motor are given and test results validate the theoretical performances.

The predictive Control based speed, flux and torque prediction of a double stator induction motor is proposed in this research paper; the model of the DSIM and the Direct vector Control of the system have performed, subsequently, the classical PI Controllers for the speed Control, the flux, and thus for setting the stator’ s currents have adopted. In order to minimize the transient Control and to reduce the impact of measurement noise on the Control signal, instead of vector Control technique which requires the flux and torque estimation, the multivariable generalized predictive Control is used. The results have shown the effectiveness of the proposed method, especially in the parameters variation and/or the change of the reference speed.
