Boost变换器的抗扰动复合控制
为了探究Boost变换器中的扰动对升压的稳态和动态性能的影响，依据变PI （ VAPI ）控制理论和扰动观测理论提出了一种复合控制方案。首先，采用变PI控制方法设计状态反馈控制器，以提高Boost变换器的动态性能。其次，采用扰动观测器（ DOB ）观测Boost变换器中的扰动，从而得到扰动的估计值。最后，将该估计值作为前馈补偿到输入端，与变PI状态反馈相结合形成反馈加前馈的复合控制方案。仿真和实验表明，当存在输入电压突增、输入电压突降、负载突变等扰动时，与变PI控制相比，变 PI ＋DOB 的复合控制方案可以使得闭环系统具有更好的动态和稳态性能。...

| Abstract_FL | In order to explore the disturbance effect on the dynamical and steady performance of a boost converter. A composite control strategy was proposed by combining the variable parameter PI ( VAPI) control theory and disturbance observation theory. First of all, the VAPI controller was designed to im-prove the dynamic performance of the Boost converter. Then, the disturbance observer was adopted to es-timate the disturbance of the Boost converter, and thus the estimated value of disturbance was obtained. Finally, taking the estimated value as the forward compensation, combined with the feedback VAPI con-troller, a composite control scheme was obtained. Simulation and experiments show that compared with VAPI controller, the composite controller ensures much better dynamical and steady behavior in the pres-ence of input voltage surge, input voltage dip and load mutation. |
