摘要
为保证DC/DC变换器输出稳定电压并具有较快的响应速度,需要对DC/DC变换器进行建模,由于DC/DC变换器具有非线性、时变等特点,为此本文通过基本建模法对系统进行交流小信号分析,用该方法获得控制对象的传递函数,并利用补偿网络形成电压电流双闭环控制系统,通过MATLAB对控制方法进行仿真,验证补偿网络参数设计的可行性。
In order to ensure the DC/DC converter output voltage stability and has faster response speed, it need to model the DC/DC switch converter, and DC/DC converter is nonlinear, time-varying characteristics.ln this paper, we can through the basic modeling method of the system of AC small signal analysis, control object transfer function, and the use of compensation network to form a voltage and current dou- ble closed-loop control system, the control method is emulated by MATLAB, whitch Verify the feasibility of the system modeling design.
