移动电站励磁系统L2干扰抑制控制策略设计

摘要

In view of the interference suppression insufficiency of excitation control system in traditional mobile power stations, this paper adopts a design based on backstepping method and takes nonlinear characteristics of small power systems into consideration, obtaining the interference suppression control law for the power station excitation system. Simulation analysis and experiment plot observation shows the obtained control law has strong interference suppression capabilities, therefore realizes control robustness and greatly improves the performance of mobile power station.%针对传统移动电站励磁系统控制干扰抑制的不足，采用了基于Backstepping的设计方法，充分考虑移动电站小型电网络的非线性特性，得到了电站励磁系统L2干扰抑制的控制规律。经过仿真对比分析，观察得到的实验图形，验证了所得到的控制规律对于干扰具有较强的抑制能力，能够实现系统的鲁棒控制，大大提高移动电站的整机性能指标。
