Research on Sliding Mode Control Strategy for Bidirectional DC/DC Energy Storage Converter

摘要

In order to solve the problem that the two-way energy storage converter has a slow start-up response and poor anti-disturbance, this paper according to the nonlinear characteristics of the bidirectional DC/DC converter, the affine nonlinear system model is established to achieve accurate feedback linearized Sliding mode variable structure control Strategy. And compared with the double closed-loop PI control method. The results show that under the disturbance of external load and input voltage, the control strategy has fast response and strong robustness.
