研究静止无功发生器(SVG)的非线性控制.分析了SVG在dq坐标系中的数学模型,针对该系统的强耦合性及非线性,提出采用状态反馈线性化对系统进行精确线性化处理,并进一步将滑模控制引入到线性化处理后的系统当中,提出一种改进的变速趋近律,结合空间矢量脉宽调制技术(SVPWM),完成系统控制器的设计,同时对直流侧电压控制器进行了设计.通过MATLAB对改进的控制系统与传统PI控制进行了仿真比较,并搭建了实验样机,验证了所提出的控制策略可行且有实用价值.“,”The static var generator (SVG) nonlinear control strategy is researched. The mathematical model of the SVG in the synchronous rotating (d-q) coordinate system is analyzed, according to the strong coupling and nonlinearity of the mode, state feedback linearization is proposed to linearize the system model exactly, and the sliding mode controller is further designed for the linearized system, an improved sliding mode control law is proposed. Combining the space vector pulse width debug technology (SVPWM), the system controller design is completed, at the same time the DC side voltage controller is designed. Finally, the simulation compared with the traditional PI control and experiment of the whole SVG system verify that the proposed control strategy is feasible and has practical value.
