Abstract :
This paper describes and investigates different dynamic overmodulation strategies applied to highly dynamic current control of interior permanent magnet synchronous machines. Although the machine is highly utilized, which indicates significant saturation characteristics, a linearized PI-Controller with excellent dynamic performance is used. The impact of voltage limitation with use of overmodulation on the current control quality is investigated and described.
