The slip angular frequency can be written as: Estimated torque response when step load torque change from no-load to full load 0—12 Nm with proposed DTC. Generally, in a symmetrical three phase induction motor, the instantaneous electromagnetic torque is proportional to the cross-sectional product of the stator flux linkage space vector and the rotor flux linkage space vector. Direct Download Success Stats: National Institute of Technology, Warangal , A. Estimated actual flux magnitude is: By introducing more than one vector within the sampling period, reduction of the torque ripple can be achieved.

This paper proposes an algorithm for direct flux and torque controlled three phase induction motor drive systems.

The slip angular frequency can be written as: Additional titles containing download driver dtc dq u2. This technique gives better performance in three-phase induction motor than conventional technique.

This method is based on control of slip speed and decoupled between amplitude and angle of reference stator flux for determining required stator voltage vector. By using space vector modulation technique in DTC, the sampling frequency is maintained constant and reduced torque ripple with low switching losses. Simulation results of conventional DTC: If you encounter problems with the direct download for these operating systems, please consult the driver download manager for the specific Dtc Dq U2 Usb Serial Port model.

By substituting Equation 11 into 10the modified instantaneous electromagnetic torque is given by: Reasons for your score: Block diagram of the Proposed DTC. Direct Stator Flux Control Method. Finally my PC got up to speed! It represents the motor developed torque at no-load and full load, stator flux and stator current at rated speed for conventional DTC and proposed DTC drives.

Space Vector Voltage and Switching Pattern. In this conventional DTC, at every sampling period, the stator flux linkage errors and torque errors are kept within required tolerance band and can be achieved by optimal switching state vectors. It is proposed a decoupled control between the amplitude and angle of stator flux for generating the pulses for Dfc.

Using this reference voltage components, time signal are calculated as explained in [8]. National Institute of Technology, WarangalA. Figure 2 shows that the flux magnitude, direction and torque angle will depend on voltage space vectors of the vtc.

From simulation results, the proposed technique showed that the stator current, flux linkage and torque ripples are lesser than in the conventional technique.

The reference flux vector is given by: Required slip angel is written by: More Synaptics Pointing Device Driver The circuit diagram of a conventional DTC is shown in Figure dtf. By introducing more than one vector within the sampling period, reduction of the torque ripple can be achieved.

The conventional and proposed DTC simulation results are presented and compared. Within the given sampling time, flux as well as torque errors are controlled by stator voltage vector which is evaluated from reference stator flux. From 7 torque equation is replaced as 8 using the same principle in [5] and [6], the instantaneous electromagnetic torque can be derived as: From Equation 12the instantaneous electromagnetic torque control is performed by changing the value of slip angle witch is controlled by using direct stator flux control method.
