从两个方面研究了非线性静止无功补偿器(SVC)系统的自适应反推控制器设计问题。首先,而不是人为地假设一个上限或不等式标度,极大极小理论被用来处理外部未知的干扰。由于考虑了最坏情况的干扰,系统对大干扰的影响不敏感。其次,在自适应控制中引入参数投影机制,使参数估计值在预先指定的区间内。该控制器在不影响控制平滑性的前提下处理了非线性参数化问题,同时提高了参数估计速度,增强了系统的鲁棒性。考虑短路接地故障和机械功率扰动,进行了仿真研究。仿真结果表明了该控制方法的有效性。
The problem of designing an adaptive backstepping controller for nonlinear static var compensator (SVC) system is addressed adopting two perspectives. First, instead of artificially assuming an upper bound or inequality scaling, the minimax theory is used to treat the external unknown disturbances. The system is insensitive to effects of large disturbances due to taking into account the worst case disturbance. Second, a parameter projection mechanism is introduced in adaptive control to force the parameter estimate within a prior specified interval. The proposed controller handles the nonlinear parameterization without compromising control smoothness and at the same time the parameter estimate speed is improved and the robustness of system is strengthened. Considering the short-circuit ground fault and mechanical power perturbation, a simulation study is carried out. The results show the effectiveness of the proposed control method.
