摘要
研究包含有LCL滤波的STATCOM的控制器设计,文中建立STATCOM在dq坐标下的6阶系统数学模型,并将其分解了两部分进行控制设计,应用逆系统理论完成系统的解耦和线性化,然后设计其改进滑模控制策略,最后通过仿真实验并与传统PI控制进行了对比,结果验证了本文设计方法的正确性和高效性。
The paper researches the control strategy of STATCOM with LCL filter.The STATCOM sixth orders differential equations in dq coordinate separate to two parts.Invert system theory deals with their uncoupling and nonlinearity.Then the modified sliding mode control strategies were used to the differential equations.Finally simulation results showvalidity and effectiveness of the design by comparing with PI controller.
