High performance control of a boost AC-DC PWM rectifier-induction generator system

This paper presents a control methodology for the dc voltage regulation of an induction generator-ac-dc- boost rectifier system in which the copper loss of the generator is minimized. With the aid of an input-output linearization technique, which linearizes and decouples the model equations in the synchronous reference frame, a rotor flux vector control type high performance is achieved. Steady-state analysis provides some insights into the operability regime of the generator. The effectiveness of the control scheme under different load conditions as well as varying rotor speeds has been demonstrated by computer simulations. Some experimental results are included.
