Abstract:
      The control method forafull-bridge DC/DC converter system is studied in this paper. In view of the present status of the existing DC/DC converter, such as a slow dynamic response speed and poor anti-interference capability, adynamic matrix control-proportional integral differential(DMC-PID) cascade control method based on state feedback linearization is proposed. The state space average method is used to establish a nonlinear model of the full-bridge DC/DC converter system. By applying state feedback linearization, a linear system is obtained. To empower the system with excellent control performance, the DMC-PID cascade control method is selected. This control method not only has the robustness of the PID algorithm, but also has the rapidity and stability of the DMC algorithm, which can effectively solve the problem that the output voltage cannot be kept stable in time when the input voltage fluctuates in a wide range.Through simulation analysis and experiments, it was proved that the proposed scheme can achieve accurate and fast control of the converter output under various disturbance conditions.
