Control of power electronic converters is an application area where system identification is necessary due to the implementation of suitable controllers. Thanks to the identification process, it is possible to obtain a suitable mathematical model of the converter, which can be used for the design of its control. This article deals with the design of a new recursive–iterative identification method applicable in practice. The method has the task of finding a parametric model. The converter plant linear time-invariant model is found and described mathematically by its transfer function. The method is verified by simulation and also on a real sample of a synchronous buck converter.

电力电子转换器的控制是一个应用领域，由于实施了合适的控制器，因此必须进行系统识别。借助识别过程，可以获得转换器的合适数学模型，该数学模型可用于其控制的设计。本文讨论了在实践中适用的新的递归-迭代识别方法的设计。该方法的任务是找到参数模型。转换器工厂的线性时不变模型可以通过其传递函数找到并进行数学描述。该方法通过仿真以及同步降压转换器的实际样本进行了验证。
