针对配电网静止同步补偿器(distribution static synchronous compensator,D-STATCOM)系统非线性、多变量、强耦合特性、D-STATCOM系统模型的不确定性和不确定性干扰对D-STATCOM控制的影响,研究了D-STATCOM的自抗扰控制技术,提出了一种新型的D-STATCOM自抗扰控制策略,当D-STATCOM系统参数发生变化或遇到不确定扰动时,D-STATCOM控制器仍能保持良好的控制性能以及强的自适应性和鲁棒性。给出了控制器设计的详细过程,并在MATLAB/Simulink环境中建立了系统的仿真模型,给出了仿真和实验结果。仿真和实验结果证明了自抗扰控制策略的正确性和有效性。
Aiming at the nonlinear, multivariable and strongly coupled system of distribution static synchronous compensator (D-STATCOM) system, the influence of the uncertainty and uncertainty of D-STATCOM system model on the D-STATCOM control , Studied D-STATCOM ADR control technology, proposed a new type of D-STATCOM ADR control strategy, when the D-STATCOM system parameters change or encounter uncertain disturbance, D-STATCOM controller is still Can maintain good control performance and strong self-adaptability and robustness. The detailed process of controller design is given and the system simulation model is established in MATLAB / Simulink environment. Simulation and experimental results are given. Simulation and experimental results show the correctness and effectiveness of ADRC control strategy.
