Dynamic Compensation Control of Buck-type Bidirectional DC-DC Converter Based on Model Predictive Control
针对直流微电网中负载投切、功率波动和二倍频注入导致的直流电压波动问题,提出了一种基于模型预测控制的Buck型双向DC-DC变换器动态补偿控制策略.首先,建立Buck型双向DC-DC变换器的离散状态空间矩阵,并以输入电流为扰动量.其次,设计Buck型双向DC-DC变换器的基于模型的内环电流预测控制和外环电压控制.然后,针对电流扰动设计基于残差生成器的动态补偿控制结构,并求解动态补偿控制器Q(z),同时利用最小二乘递推算法进行参数辨识,减少模型不确定…查看全部>>
Aimed at the problem of DC voltage fluctuations caused by load switching,power fluctuations and dou-ble-frequency injection in DC microgrids,a dynamic compensation control strategy for a Buck-type bidirectional DC-DC converter based on model predictive control(MPC)is proposed.First,the corresponding discrete state space matrix is es-tablished,and the input current is used as the disturbance.Second,the model-based inner-loop current predictive control and out…查看全部>>
