| Abstract |
The paper presents a linearized and input-output decoupled model of induction motors obtained through a nonlinear state feedback. This approach has made it possible to carry out a simple model of the motor constituted by two lines of double integrators. In addition, the determination of the components of the motor supply voltage - on the basis of the model inputs and machine state values - does not involve heavy computations. Besides showing the methodology, the paper also analyzes the effects due to variations in the most significant electromagnetic and mechanical parameters and presents the results of some simulations in which a classical PI controller and a tachometer feedback have been adopted as control system. The availability of a simple equivalent model for the induction motor allows the use of more sophisticated control techniques, that the authors are investigating. |
