| 推进负载对船舶电网的暂态稳定性影响是船电系统的主要特征之一. 本文基于非线性鲁棒L2干扰抑制控制方法, 研究了具有螺旋桨负荷的船舶电力系统中的励磁与调速的协调控制问题, 在充分分析了柴油发电机组的非线性数学模型及其螺旋桨负载的相互耦合的非线性动态结构特性的基础上, 提出backstepping控制技术与L2干扰抑制相结合的综合协调控制策略来设计控制器. 该控制器在保证系统稳定的条件下, 有效地抑制干扰对发电机系统电压和频率的影响. 仿真表明, 在给系统突加螺旋桨负载的情况下, 该控制器能有效地抑制负载对系统性能的影响, 验证了控制器的有效性. |
| 英文摘要 |
| One of the main characteristics is the effect of propellers on transient stability of ship power systems. Based on L2 disturbance attenuation control method, this paper investigates the coordinate control design for the excitation and speed regulator of ship power systems with propeller loads. Considering nonlinearities and coupling interactions between propeller loads and the marine diesel engine generator, we propose an integrated control scheme combining backstepping technique with L2 disturbance attenuation method. The controller not only stabilizes the system but also attenuates the disturbance influences on the voltage and frequency of the generator. Simulation shows excellent suppression of the effect on the transient performances of the generators when a load is abruptly applied to the propeller. |
