摘要
针对TL-Boost变换器多模态、时变、非线性的工作模式,难以对其进行建模与控制的问题。本文通过对变换器电路的工作原理进行分析,采用状态空间平均小信号建模方法对变换器的控制至输出进行数学建模,得到相应的传递函数。通过对传递函数进行分析,设计了无源超前网络对电路进行校正,构建了闭环控制系统。为验正控制器效果,建立仿真模型观察在输入电压扰动及负载扰动工作情况,结果表明所设计控制器具有良好的控制性能。
For the multi-modal,time-varying and nonlinear working modes of TL-Boost converters,it is difficult to model and control them.In this paper,by analyzing the working principle of the converter circuit,the state space average small signal modeling method is used to mathematically model the control to output of the converter,and the corresponding transfer function is obtained.By analyzing the transfer function,a passive advanced network is designed to correct the circuit and a closed-loop control system is constructed.In order to verify the effect of the controller,the simulation model was established to observe the input voltage disturbance and load disturbance.The results show that the designed controller has good control performance.
