The Given

This paper presents an implementation of adaptive dual current mode control (ADCMC) on non-inverting buck-boost converter. A verification of the converter operation with the proposed ADCMC has been performed in steady state and during the disturbances in the input voltage and the load resistance. The given simulation and experimental results confirm the effectiveness of the proposed control method.

Squirrel Cage Induction Generator

In this paper, a nonlinear controller is proposed to manage the rotational speed of a full-variable Squirrel Cage Induction Generator wind turbine. This control scheme improves upon tractional vector controllers by removing the need for a rotor flux observer. Additionally, the proposed controller manages the performance through turbulent wind conditions by accounting for unmeasurable wind torque dynamics. This model-based approach utilizes a current-based control in place of traditional voltage-mode control and is validated using a Lyapunov-based stability analysis. The proposed scheme is compared to a linear vector controller through simulation results. These results demonstrate that the proposed controller is far more robust to wind turbulence than traditional control schemes.
