本文研究了电流模式 H 桥逆变器简化模型中低周期不稳定周期轨道 (UPO) 的稳定性。逆变器的开关由脉宽调制信号控制,具体取决于采样的电感器电流。该逆变器可以表现出丰富的非线性现象,包括倍周期分岔和混沌。我们的控制方法是通过在目标UPO过零时刻电感瞬时打开来实现的,原则上只要UPO过零就可以瞬时稳定UPO。典型的系统操作可以通过数值实验来确认。
This paper studies stabilization of low-period unstable periodic orbits (UPOs) in a simplified model of a current mode H-bridge inverter. The switching of the inverter is controlled by pulse-width modulation signal depending on the sampled inductor current. The inverter can exhibit rich nonlinear phenomena including period doubling bifurcation and chaos. Our control method is realized by instantaneous opening of inductor at a zero-crossing moment of an objective UPO and can stabilize the UPO instantaneously as far as the UPO crosses zero in principle. Typical system operations can be confirmed by numerical experiments.
