新型改进内模解耦控制的STATCOM电流环控制方案设计
Current Loop Controller Design of STATCOM Based on the New Improved Internal Model Decoupling Control
摘要
Abstract
The mathematical model of static synchronous compensators in the d-q coordinate system was a nonlinear coupling system.The cross decoupling control was difficult to adapt the model mismatch conditions.The internal model control was robust for system parameters,but it had the transient oscillation problem.A new internal model controller was presented.Firstly,the mathematical model of cross decoupling control and internal model control was analyzed and the current transient oscillation is deduced.Secondly,the active disturbance rejection control was used to replace the internal model decoupling integrator.The extended state observer and nonlinear state error feedback were used to avoid the problem of transient oscillation.A new nonlinear state error feedback fimction fall() was proposed.The stability of the new active disturbance rejection controller usingfall() was proved by a linearization scheme.Finally,the simulations and experiments of cross decoupling,conventional internal model decoupling and the new internal model decoupling were compared.Results show that the response of the new deeoupling scheme is the best and it has stronger robustness.关键词
