摘要
在滑模控制时,三相可控整流器受整流器功率脉动向量的影响,会降低滑模控制效果。针对此问题,提出一种含不平衡负载的三相可控整流器端末滑模控制技术。在整流器拓扑结构分析的基础上建立整流器数学模型,并以此为依据分析影响滑模控制的影响因素。将滑模控制过程中不平衡负载引起的脉动向量作为必要条件,获取整流器端末滑模控制律以及滑模运动方程,完成整流器端末滑模控制器设计;利用设计的控制器实现电网不平衡负载状态下三相可控整流器端末滑模控制。试验结果表明,所提技术的控制效果较好,具有可行性。
In sliding mode control of three-phase controllable rectifier,the effect of sliding mode control may be reduced due to the influence of rectifier power pulsation vector.In order to solve this problem,the terminal sliding mode control technology of three-phase controllable rectifier with unbalanced load is proposed.Based on the analysis of rectifier topology,a mathematical model of rectifier is established,and the influencing factors of sliding mode control are analyzed.Taking the pulsation vector caused by unbalanced load in the process of sliding mode control as the necessary condition,the rectifier terminal sliding mode control law and sliding mode motion equation are obtained,and the rectifier terminal sliding mode controller design is completed.The terminal sliding mode control of three-phase controllable rectifier under unbalanced load of power grid is realized by the designed controller.The experimental results show that the control effect is good and feasible when the rectifier sliding mode control is carried out by the proposed technology.
