| 摘 要： | 由于开关器件的存在,DC/DC变换器作为一种强耦合、强非线性的装置.可将静态非线性特性和动态线性特性分开考虑.提出了一种采用Hammerstein模型建立DC/DC变换器数学模型的方法.该方法从输入、输出信号的相关函数出发,采用m3序列作为输入信号,从而建立变换器的Hammerstein数学模型.最后,以CUK变换器为例,在Matlab/Simulink中通过仿真验证了提出的方法是有效的.

| Abstract: | The converter is widely used in the power field,and with its nonlinearity,this device is difficult to analyze and design.This paper proposes a model of the converter using black-box methods.For a DC/DC converter,the static nonlinear characteristics and dynamic linear characteristics can be considered separately,so a Hammerstein model can be used to identify the static nonlinearity from input-output measured at the steady state.A linear model is used to identify the dynamic linear part from input-output data... |
