| 摘 要： | 滑模变结构控制理论在电力系统控制中获得了广泛应用，但其在实际应用中存在抖振，无法满足系统要求，将高阶滑模控制应用于同步发电机励磁系统解决了抖振问题．首先将同步发电机的数学模型变为奇异摄动非线性系统，然后分别对快变和慢变子系统进行滑模控制设计．由于系统状态的不可测性，利用次最优算法保证滑模的存在，使系统渐近稳定．仿真结果证明该算法的有效性．

| Abstract: | Because of the chattering in sliding mode control, the application of sliding mode can't meet the practical demands very well, although it is widely used in electric power system control. Here, applying the high-order sliding mode control to the synchronous generator system can solve this problem. Firstly, transform the model of the synchronous generator to the singular perturbation nonlinear system. Then, design the sliding mode controllers for both fast and slow subsystems. Due to the non-measurability of the system states, the suboptimal algorithm is applied to ensure the existence of the high-order sliding mode and make the system asymptotically stable. The simulation results demonstrate the effectiveness of the algorithm. |
