| 中文摘要 |
| 独立电力系统的稳定性主要取决于柴油发电机组的转速和电压响应特性. 柴油发电机组控制系统是一个非线性控制系统, 转速和电压相互作用, 对二者进行综合控制非常必要. 为了分析系统的动态特性,首先建立柴油发电机组的非线性数学模型, 然后以此为基础设计非线性H2/H∞综合控制器. 将直接反馈线性化和混合H2/H∞控制理论相结合应用于柴油发电机组综合控制器的设计, 把系统的性能要求转化为标准H2/H∞控制问题, 获得了柴油发电机组非线性H2/H∞综合控制律. 计算机仿真结果表明, 设计的非线性H2/H∞综合控制器有效地提高了系统的动态精度和抑制扰动的能力, 改善了独立电力系统的稳定性. |
| 英文摘要 |
| The stability of an isolated power system is determined by the speed and voltage response characteristic of the diesel-generator set. The control system of a diesel-generator set is a nonlinear control system. Because of the interaction between speed and voltage, it is necessary to control them synthetically. To analyze the dynamic characteristics of this system, a nonlinear mathematical model of diesel-generator set is built first, and a nonlinear H-two/H-infinity synthetic controller is then designed. In combining the direct feedback linearization with the mixed H-two/H-infinity control theory to design the synthetic controller for the diesel-generator set, the specifications of the system are transformed to that of a standard H-two/H-infinity control problem, and a nonlinear H-two/H-infinity synthetic control law is developed for the diesel generator set. The computer simulation results show that the nonlinear H-two/H-infinity synthetic controller effectively improves the dynamic precision of the system and suppresses the load disturbance, thus providing desirable stability for an isolated power system. |
