Direct Torque Control of Induction Motors - High-Performance Control Model

Direct Torque Control (DTC) of induction motors represents a highly practical technology that enables more precise and efficient motor control. DTC is a technique that directly regulates motor torque by controlling stator flux and electromagnetic torque through instantaneous voltage vector selection, eliminating the need for complex coordinate transformations used in traditional Field-Oriented Control (FOC). Compared to indirect torque control methods, DTC offers superior dynamic response, faster torque response times, and enhanced control accuracy. The implementation typically involves hysteresis controllers for torque and flux regulation, along with optimal switching table-based voltage vector selection algorithms.

In modern industrial applications, induction motors find extensive usage across various sectors including petroleum, chemical processing, energy generation, and transportation systems. Understanding DTC technology for induction motors not only enhances your expertise in advanced motor control techniques but also provides significant advantages in industrial applications, establishing a solid foundation for professional development. From a programming perspective, DTC implementation requires careful consideration of sampling rate selection, flux and torque estimation algorithms using voltage and current measurements, and robust switching logic to minimize torque ripple.
