Integrated Field-Weakening and MTPA Control with Adaptive Overmodulation for IM Drives
Original language description
This paper presents a comprehensive field weakening (FW) control strategy for Induction Machine (IM) drives that integrates Maximum Torque per Ampere (MTPA), torque maximization in FW, and adaptive overmodulation. The method combines FW and MTPA using a priority-based approach to optimize efficiency at light loads and maximize torque under voltage constraints in the II. FW region. Linear modulation is prioritized to reduce torque ripple and losses, with overmodulation, based on Bolognani's method, activated only when necessary. A maximum voltage controller enables smooth transitions between linear, overmodulated, and six-step operation by dynamically adjusting the voltage margin. The system, built on direct rotor flux-oriented control, includes enhanced machine modeling with iron loss and parameter adaptation. Experimental results on a 12-kW SiC-inverter-fed IM validate the strategy, making it suitable for various applications, including electric traction. While the individual methods are well documented, their comprehensive integration within a single control structure remains relatively underexplored.
