This book focuses on modern control strategies for interior permanent magnet (IPM) machines used in real-world drive applications. It addresses key challenges encountered in high-performance IPM drives, including parameter nonlinearities, inverter-based effects, and operating constraints over wide speed operating ranges. Field Oriented Control and Direct Torque Control schemes are systematically analyzed with an emphasis on implementation aspects rather than ideal assumptions. High-efficiency operation through Maximum Torque per Ampere, Field Weakening, and Maximum Torque per Voltage strategies is discussed in detail. The book serves as a practical reference for engineers and researchers involved in electric vehicle traction applications and advanced motor drive systems.
