Vector Control (motor) – Wikipedia, The Free Encyclopedia
Field-oriented control or vector control is "a math-intensive technique for controlling brushless dc and ac induction motors" that "reduces motor size, cost and power consumption" and "is a a cousin of flux vector control" Field-oriented control (FOC) is very common in induction motor control due to … Read Article
