Despite two decades of massive strides in research and development on control strategies and their subsequent implementation, most books on permanent magnet motor drives still focus primarily on motor design, providing only elementary coverage of control and converters.

Addressing that gap with information that has largely been disseminated only in journals and at conferences, Permanent Magnet Synchronous and Brushless DC Motor Drives is a long-awaited comprehensive overview of power electronic converters for permanent magnet synchronous machines and control strategies for variable-speed operation. It introduces machines, power devices, inverters, and control, and addresses modeling, implementation, control strategies, and flux weakening operations, as well as parameter sensitivity, and rotor position sensorless control. Suitable for both industrial and academic audiences, this book also covers the simulation, low cost inverter topologies, and commutation torque ripple of PM brushless DC motor drives. Simulation of the motor drives system is illustrated with MATLAB codes in the text.

Krishnan has been granted seven US patents and many are pending in US, Europe and other countries. His inventions have been prominently featured in public media including radio, TV, and newspapers such as The Wall Street Journal. He has consulted extensively for 18 companies in USA. He has developed and delivered short courses for academia and industry on vector controlled induction, permanent magnet synchronous and brushless dc, switched reluctance and linear electric motor drive systems.

The BLDC motor is a combination of a permanent magnet synchronous motor, a solid state inverter, electronic control circuitry and rotor position sensors (Singh and Bist, 2013; Kim and Youn, 2002). The inverter together with its control unit and rotor position sensor of BLDC motor imitates the mechanical commutation of DC motor and which is named as electronic commutation (Pillay and Krishnan, 1989; Pillay and Krishnan, 1988). There are basically two categories of BLDC motor viz. permanent magnet synchronous motor (PMSM) and BLDC motors depending on their back-emf wave shape. The one which has six-step trapezoidal wave shape is called as BLDC motors in which stator consists of three phase concentrated winding and rotor with permanent magnets and the PMSM has sinusoidal back-emf where in stator consists of three phase distributed winding and rotor with permanent magnets (Pillay and Krishnan, 1989). To improve the performance of the drive, the researchers are mainly concentrating on speed control methods, torque ripple minimization, inverter topologies and design of the front converters (Xie et al., 2013; Aydogmus and Sunter, 2012; Gargouri, 2012; Yildiz, 2012; Liu et al., 2010; Lee and Noh, 2011; Im et al., 2010; Baratam et al., 2014; 2ff7e9595c
