| 摘 要： | 以改进幂次趋近律滑模控制的H桥逆变器为例：首先,运用频闪映射理论建立数学离散模型;其次,采用频闪图和频谱图观察到系统工作在不同控制参数k1和k2作用下的非线性动力学行为;再次,运用快变稳定性定理对系统工作稳定性进行理论分析,研究的结论与频闪图及频谱图的分析完全一致;最后,研究发现输入电压E、负载电感L与电阻R等外部电路参数的变化,对系统的稳定性能有重要的影响。

| Abstract: | The H-bridge inverter with sliding mode control based on improved idempotent approach law was taken as an example. Firstly, the discretized mathematical model of the system is established by using the stroboscopic mapping theory. Secondly, the nonlinear dynamic behavior of the system under different control parameters and was observed by stroboscopic diagram and spectrum diagram. Thirdly, the stability of the system was analyzed by using the fast-varying stability theorem, and the study conclusion is completely consistent with the stroboscopic diagram and spectrum chart analyses. Finally, the study showed that changes of external circuit parameters, such as, input voltage, load inductance and resistance have important effects on the stability of the system. |
