摘要

摘要: 为解决轨道交通供电负载频繁波动使得系统输出恒压困难的问题，提出了基于滑模控制和PI控制的双环控制策略.首先对原边建立离散时间动态模型、副边采用大信号模型分别进行建模；其次，基于系统建模设计双环控制策略，采用滑模控制控制电流内环、PI控制控制电压外环；最后，对设计的双环控制进行了实验验证.验证结果表明：恒压下进行70 Ω和50 Ω电阻切换时，电压变化约5%，并在15 ms左右恢复到稳定值，因此，在负载波动的条件下该控制策略能保证输出电压恒定和快的响应.

Abstract: To solve the problem of constant voltage output due to frequent load fluctuations in rail transit power supply systems, a dual-loop control strategy based on sliding mode control and PI control is proposed. First, the authors established a model for the system with a discrete time dynamic model for the primary side, and a large signal model for the secondary side. Second, a dual-loop control strategy based on the model is proposed, in which the internal current loop is controlled by sliding mode control and the external voltage loop is controlled by the PI controller. The test results show that when switching the resistance to between 70 Ω and 50 Ω under a constant output voltage, the voltage changes by about 5% and returns to a stable value in approximately 15 ms. Therefore, the proposed control strategy can ensure a constant output voltage and fast response times under frequent load fluctuations.
