摘要
针对传统双有源桥(DAB)DC/DC变换器控制策略由于调节时间过长导致其动态响应能力较差的问题,提出了基于开环估计补偿的DAB无偏模型预测控制策略。所提控制方法基于DAB状态空间模型进行控制建模并采用开环估计补偿以消除模型误差,然后利用滚动优化算法求解代价函数来获得最优化控制效果。仿真和实验结果表明所提DAB控制方法控制效果好、电压常值跟踪能力强且动态响应迅速。
To address the problem that the traditional dual active bridge(DAB)DC/DC converter control strategy has poor dynamic response ability due to long regulation time,an open-loop estimation compensation based DAB offset-free model predictive control strategy is proposed.The proposed control method is based on the DAB state space mod-el to control and model and adopts open-loop estimation compensation to eliminate the model error,and then uses a rolling optimization algorithm to solve the cost function to obtain the optimal control effect.Simulation and experimen-tal results show that the proposed DAB control method has good control effect,strong voltage constant tracking capa-bility and rapid dynamic response.
