摘　　要：对由晶闸管控制电抗器 (TCR)型装置与多个晶闸管开关电容器 (TSC)型装置组成的静止无功补偿系统 (SVC)建立了一个新的非仿射非线性模型。该模型以晶闸管的触发角为控制量。根据非线性控制的逆系统方法 ,设计了相应的非线性反馈线性化和极点配置的组合控制器。在控制器的设计中利用插值法导出了一个超越方程解函数的具有较高精度的近似计算公式。仿真结果表明了该设计方法的正确性和有效性。This paper designs TCR TSC SVC controller based on non affined nonlinear model. The trigger angle of thyristor is selected as the control variable in the model. Using the inverse system method, a controller composed of the linearization of nonlinear feedback and pole assignment is designed. An approximate formulation with sufficient high precision is obtained from an implicit function in designing the feedback linearization control law. The simulation results show the correctness and effectiveness of the proposed method.
