摘要

提出了一种改进的基于参数估计的预测电流控制方法。用离散时间模型预测了电网电流的未来值。利用质量函数对栅极电流的预测值进行评价。选择质量函数最小的最优开关状态。预测电流控制对参数的变化很敏感。通过参数估计来补偿参数值变化对控制系统的影响。参数估计采用最小二乘法实现。将估计的参数应用到预测模型中,提高了控制系统的精度。

Improved predictive current control by parameter estimation in grid connected inverter applications
An improved predictive current control through parameter estimation is presented. The future value of grid current is predicted by a discrete-time model. The predicted value of grid current is evaluated by the quality function. The optimal switching state that minimizes the quality function is selected. The predictive current control is sensitive to variations in parameters. The effect of variations in parameter values on control system is compensated by parameter estimation. The parameter estimation is achieved by the least square method. The estimated parameters are applied to predictive model and it improves an accuracy of control system.
