摘　　要：船舶电力系统的稳定性主要取决于船舶电站柴油发电机组转速和电压的响应特性,转速和电压相互作用,对两者进行综合控制非常必要。本文将混合H_2/H_∞控制理论应用于柴油机调速系统的设计,将柴油机调速系统的性能要求转化为标准混合H_2/H_∞控制问题。计算机仿真结果表明,利用线性矩阵不等式(LMI)方法所设计的混合H_2/H_∞调速器能在考虑模型不确定性的情况下,有效地提高系统的动态精确度和抑制扰动的能力,解决了转速和电压的综合控制问题,改善了船舶电力系统的稳定性。The stability of a ship power system is mainly decided by the speed and voltage response characteristic of diesel-generator set in ship power station.Because of the interaction between the speed and voltage,it is necessary to control them synthetically.In this paper a diesel-generator set synthetic control system is designed by means of mixed H_2/H_∞control theory,which transfers the specifications of system into a standard mixed H_2/H_∞control problem.The computer simulation result showed that the mixed H_2/H_∞speed governor designed by the linear matrix inequality approach would improve the dynamic precision of system and the ability to restrain the load disturbance in case of considering system model uncertainty.The synthetic control problem of the speed and voltage can then be solved,and the stability of ship power system is improved。
