摘要
This paper proposes a control strategy for a step-down Buck power converter with LCL output filter feeding a constant power load. The control strategy uses exact feedback linearization, including the power estimation of the load. This allows to obtain fast response when the power demanded changes between different values. The power estimate is obtained by using a non-linear reduced-order observer with linear error dynamics. Hence, the control strategy uses a reduced number of sensors, increasing reliability and reducing the cost of the system. The system performance obtained with the proposed control strategy is tested through numerical simulations.
