Adaptive Active Disturbance Rejection Control of DAB Based on PSO

Dual active bridge (DAB) converter has become a promising solution to integrate batteries and renewable energies into DC microgrids (MG), which can reduce the number of power conversions. To improve the stability and robustness of DC microgrid, a particle swarm optimization based active disturbance rejection control (PSO-ADRC) approach is proposed and validated in a single-phase DAB topology. PSO method is employed as an automatic tune mechanism to update the parameters of the ADRC controller in real-time. The simulations show that the control method is robust against parameter variations and external disturbance.
