摘要

This chapter presents a comprehensive study of Direct Power Control (DPC) applied to induction motors, focusing on its ability to directly regulate active and reactive power without the need for internal current control loops. Unlike traditional Field-Oriented Control (FOC) or Direct Torque Control (DTC), DPC offers high dynamic performance with reduced complexity, making it highly suitable for industrial applications that demand rapid response and precise power regulation. This chapter delves into the fundamental principles of DPC, the development of control algorithms, and the estimation techniques essential for real-time operation. Additionally, advanced switching strategies are explored to minimize power ripple, improving overall system efficiency and response time. Simulation results are provided to demonstrate the efficacy of DPC in induction motor drives under various operating conditions.
