摘要
建立单相PWM(Pulse Width Modulation, PWM)整流器欧拉-拉格朗日(Euler-Lagrange, EL)系统状态平均模型,采用阻尼注入方法设计了无源性控制器,实现系统输入单位功率因数和输出直流电压的恒定。该方法从能量角度分析单相PWM整流器的控制系统,适当配置系统能量耗散方程中的"无功力",通过能量重构和注入阻尼的方法,设计了全局稳定的控制律。该方法对负载扰动和参数摄动具有较强的鲁棒性,并且整个系统具有良好的静动态性能。仿真和实验结果验证了该控制策略的正确性和有效性。
In this paper, the state average model of single-phase PWM(Pulse Width Modulation, PWM) rectifier Euler-Lagrangian(Euler-Lagrange, EL) system is established, and the passive controller is designed by damping injection method, which realizes the constant input unit power factor and output DC voltage of the system. In this method, the control system of single-phase PWM rectifier is analyzed from the point of view of energy, the non-work force in the energy dissipation equation of the system is properly configured, and the control law of global stability is designed by means of energy reconstruction and injection damping. The whole system has good robustness for the load disturbance and parameter perturbation and it can hold nice dynamic and static performance.The simulation and experimental results verify the validity and effectiveness of the control strategy.
