摘要
以有源箝位正激变换器为研究对象,根据状态空间平均模型,建立系统误差模型,通过配置系统能量耗散特性方程中的"无功力",保证系统的无源性,设计了一种无源化控制器。论文给出了变换器无源控制方法的推导过程和有源箝位正激变换器的无源控制策略;仿真和实验结果表明,该方案运行稳定,具有较强的鲁棒性、快速性和跟踪性,且纹波较小,控制算法简单等优点。
Taking active clamp forward convert as research object,the error model of system was established based on the state space average model.Then the passivity of system was proofed and one controller was designed by deploying the no-power force in the energy dissipation equation.This paper put forward a deduction method of the passivity-based control of the converter,and hence its passivity-based control law is introduced.Simulation and experimental results show out the advantage of stable running,has strong robustness、rapidity、shadowing and small signal properties and simpler control arithmetic etc.
