Control of commuting devices can be naturally achieved by switching mechanisms, designed through relay control systems and sliding-mode control, for example. Consequently, a robust operation is guaranteed but the resulting operating switching frequency is normally high and varying. Such behavior is undesired in power electronics as it implies an increase in commutation losses, devices heating, and...
Doubly fed induction generator (DFIG) is the most implemented electric machine in wind energy conversion systems (WECS) due to reduced size converter, active and reactive power control and economic factors. However, the power electronic stage needs an accurate controller that allows to follow the stator power regulation. As a result, Sliding-Mode Control (SMC) has been successfully implemented in...
This paper presents a full real time system for educational purposes which includes the hardware and software descriptions to achieve a complete laboratory setup in order to teach induction motor drives. The induction motor drives schemes have sometimes similar operational and control blocks which can be called general blocks. In this paper the general blocks are developed and tested for generating...
