| 中文摘要 |
| 船舶电力系统频率的稳定性主要取决于船舶电站柴油机调速系统的转速响应特性. 船舶电站柴油机调速系统是一个非线性控制系统, 为了分析系统的动态特性, 首先建立柴油机调速系统的非线性数学模型, 然后以此为基础设计非线性H2/H∞速器. 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调速器的设计,把系统的性能要求转化为标准H2/H∞控制问题, 获得了柴油机非线性H2/H∞转速控制律. 计算机仿真结果表明, 设计的非线性H2/H∞调速器有效地提高了系统的动态精度和抑制扰动的能力, 改善了船舶电力系统频率的稳定性. |
| 英文摘要 |
| The frequency stability of a ship power system is determined by the speed response characteristic of the diesel engine speed regulation system, which is a nonlinear control system. To analyze the dynamic characteristic of this system, a nonlinear mathematical model is built first, and then, a nonlinear H-two/H-infinity controller is designed. In combining the direct feedback linearization with the mixed H-two/H-infinity control theory to design the speed regulator for the dieselgenerator, we transform the specifications of the system to that of a standard H-two/H-infinity control problem, and then
develop a nonlinear H-two/H-infinity speed control law for the diesel engine. The computer simulation results show that the nonlinear H-two/H-infinity speed regulator effectively improves the dynamic precision of the system and suppresses the load disturbance, thus providing desirable frequency stability for a ship power system. |
