Comparing the field oriented and direct torque vector controls applying on induction motors

چکیده
Induction motors are widely used in the industry due to its relative low cost, low maintenance and high reliability. The development of the computer and electronic industry, as well as design of new control methods, has opened the door to control induction motors. In order to control the induction motors, scalar and vector control methods are used. Vector methods have faster response and more precision in controlling electric motors than scalar methods. The two main methods for vector control of induction motors are field oriented control and direct torque control. In this paper, the FOC and DTC vector control methods are fully described and MATLAB is used to evaluate and compare these two simulation methods in Simulink environment. The simulation results show that the DTC method has more flux and torque ripple than the FOC method but eliminates the complexity and limitations of the FOC method.

Improved Direct Torque Control for Induction Machine Drives Based on Fuzzy Sector Theory
Here, a new fuzzy direct torque control algorithm for induction motors is proposed. As in the classical direct torque control, the inverter gate control signals directly come from the optimum switching voltage vector look-up table, the best voltage space vector selection is a key factor to obtain minimum torque and flux ripples. In the proposed approach, the best voltage space vector is sel...

Among all the drive control methods of induction motors, the Direct Torque Control (DTC) method operates independently of the rotor parameters of the machine and, despite its simplicity, provides good torque control in both stable and transient modes. The use of residual comparators in these drives reduces the torque ripple and variable switching frequency. The most common solution is the use o...

Induction motor drives using field oriented control (FOC) for torque and flux control have been used in high performance industrial applications instead of dc motors for many years. In FOC, torque and flux of an induction motor can be controlled independently by decoupling the stator current into its orthogonal components. The FOC method has achieved a quick torque response.

Tracking control of the direct-drive robot manipulators in high-speed is a challenging problem. The Coriolis and centrifugal torques become dominant in the high-speed motion control. The dynamical model of the robotic system including the robot manipulator and actuators is highly nonlinear, heavily coupled, uncertain and computationally extensive in non-companion form. In order to overcome thes...
