中文摘要
      无源理论是非线性系统控制和稳定性分析的重要方法之一,本文针对典型的非线性系统———DC-AC三相逆变器,提出了一种基于无源理论的控制算法.首先给出了DC-AC逆变器的欧拉-拉格朗日数学模型,即能量方程;然后将此模型变换成最小相位系统,在此基础上设计了基于无源理论的反馈控制算法,给出了闭环系统稳定性证明,保证被控系统的误差渐近收敛.仿真结果证明了所提算法具有良好的动态性能和较强的鲁棒性.
英文摘要
      A control algorithm based on the passive theory for a class of typical nonlinear system —DC-AC three_phase inverter is presented.First of all,an Euler_Lagrange mathematic model of the inverter was given,i.e.energy equation.Secondly,the model was transformed into the minimum phase system.Based_on the passive theory,the feedback control algorithm was proposed to make the controlled system asymptotically converge in the premise that the controlled system has minimum phase.The simulation results demonstrated a that the control algorithm proposed has some merits in dynamic performance and robustness.
