The application research of forward DC-DC converter control based on decaying amplification aggregation strategy in predictive control

In practical application of Model Predictive control on electronic embedded system, decreasing the on-line computation cost is important. In this paper, a decaying amplification aggregation method based Model Predictive control is proposed, where a free input followed by an amplitude decaying strategy is adopted as the control strategy of MPC. An explicit model analysis method is also presented, which could describe PWM driven system more accurate. The entire algorithm is applied on forward DC-DC converter system. The control strategy is simulated and its efficiency is validated in the MATLAB environment.
