	COMPARISON OF SEVERAL CONTROL SCHEMES FOR AC INDUCTION MOTORS UNDER STEADY STATE AND DYNAMIC CONDITIONS	[View]   [Download]
Author(s)	G. Heinemann
Abstract	In order to examine the possible use of different control schemes for AC induction motors, a comparison of the following methods was made: - field orientated control - control with given voltage to stator frequency charaderistic (Us / f1) - control with impressed stator currents and open-loop flux control (Is / f2) and a new - control scheme, proposed by R. Jönsson. The comparison is made using the same hardware equipment for an AC induction motor, inverter and microcomputer for control and includes the behaviour under steady state conditions at different speeds and loads, the sensitivity against variation in parameters of the induction motor and the dynamic behaviour at change of speed reference and mechanical load. Some of the measured results are clearified by computer simulation.
