Van Peter, the famous and adept engineer in the drive technology, wrote a practical book “Sensorless Vector and Direct Torque Control” in late 1990s that teach us how to use space vector for controlling an AC (alternating current) motor; however, we already had some motor control method such as; dq0 analysis.
In space phasor, the most recent method for motor controlling, we supplement the dq0 method by removing one coil; nevertheless, when you work with SP (Space Vector) for a while it would be hard to understand altogether.
SP method, as well as the dq0 method, let us choose the best case reference for calculation; however, it uses a remarkable creative way to control the current of the motor.
In addition to the adaptation of our motor for any situation, this control loop must be highly precise; so that, we could eliminate many errors; accordingly, we should decrease our equations of control; therefore, you must control stator’s current or rotor’s current.
In recent years vector-controlled AC drives have taken over from more conventional DC drives. Applications are found everywhere including machine tools, robotics, electric traction, and computer peripherals. Sensorless vector and direct torque control examine sensorless vector-controlled drives and direct torque controlled drives. It builds on the author’s popular Vector Control of AC Drives and brings the subject fully up to date.
If your intention is to design and control a real-world practical motor-drive go ahead and read this book because it is definitely worthy of the time. You will appreciate Professor Vas’ work when you realize that what he has collected and put together in this book about 20 years ago is still practiced in the industry and can still work fine; nevertheless, The only objections about this book would be the lack of examples and use of confusing notation.
