|Abstract ||:||Because the reluctance motors are operated at synchronous speed to be synchronizing with source frequency, so high quality speed control is made by open-loop control systems. But sometimes that speed control is impossible due to hunting which occurs depend on operating frequency and machine parameters.
Therefore, it is important problem that analysis of hunting phenomena and Stabilizing control for variable frequency operation.
In this paper, those problems are studied.
About analysis of hunting phenomena, relation of machine parameters upon hunting and region to occur the hunting is quantitatively cleared for applying Lyapunov method which is useful to analyze stability of nonlinear systems.
About Stabilizing control, more physical and simple stabilizing control is proposed, and it is verified that control is useful for variable frequency operation with various machine parameters.|
