Modeling and Predictive Control of LLC Resonant Converter for Solar Powered E-Bicycle Charging Station

Review on Modeling and Control Strategies of DC–DC LLC Converters for Bidirectional Electric Vehicle Charger Applications

“…The MPC was applied to the DC-DC LLC converter in [58] avoiding the use of a modulator. The output voltage is controlled using a predictive control strategy in order to improve the converter efficiency under light load conditions.…”

“…Simple control design Requires model knowledge PI [17,33,34] Simple gain tuning Less robust versus disturbances Low implementation cost Avoid wide control bandwidth Variation around equilibrium point Requires model knowledge GI [24] Simple control design Less robust versus disturbances Simple gain tuning Requires equilibrium point Low implementation cost More robust than linear control More complex control design MPC [58] Avoid modulator system Depends on the system model Optimization of the switching state Needs integration of all constraints Simplified model design Requires the system relative degree MFC [46] Based on estimation of a black box model Requires the output derivative Simple gain tuning Sensible to noises More robust control than linear control High implementation cost Based on sliding mode control Chattering phenomenon STC [47] More robust control than linear control Requires model knowledge Non-complicated gain tuning Higher switching losses Higher control gains More robust control than linear control Adaptive control gains More complex gain tuning ASTC [47] Reduced chattering phenomenon High implementation cost Avoid gain overestimation Requires a system relative degree equal to 1 Lower switching losses…”
