摘要

本文采用非奇异终端滑模控制(NTSMC)设计方法，研究了基于有限时间扰动观测器(FTDO)的直流微电网直流变换器系统规定性能控制器的设计方法。主要贡献是采用规定的性能控制器设计方式，实现对系统性能具体要求的布局。然后，发展FTDO来快速估计干扰，提高系统的鲁棒性。此外，考虑到系统的动态响应速度，利用NTSMC为直流变换器系统提供了参数可调的有限时间跟踪结果。最后给出了数值仿真结果，验证了所提控制器的动态性能。

Realization of Prescribed Performance Control for DC Converter System in DC Microgrid via Finite-Time Sliding Mode Observer

This paper investigates a prescribed performance controller design method for DC converter system in DC Microgrid based on finite-time disturbance observer (FTDO) by means of nonsingular terminal sliding mode control (NTSMC) design procedure. As a main contribution, prescribed performance controller design manner is employed to realize the layout of specific requirements of system performance. Then, FTDO is developed to estimate disturbances quickly and improve the robustness of the system. In addition, considering dynamic response speed of system, NTSMC is utilized to render a finite-time tracking result with tunable parameters for the DC converter system. Finally, numerical simulation results are displayed to demonstrate the dynamic performance of the proposed controller.
