摘　　要：对水下航行器热动力推进系统的非线性模型进行了线性化处理,应用线性二次型控制方法设计了系统的最优控制器,采用极点配置的方法设计了系统的状态估值器。并对系统的恒深变速过程和恒速变深过程进行了仿真计算。仿真结果表明,所设计的最优控制器取得了理想的控制品质,能够大大改善动力系统的性能。Forward the foundation and linear of the system model, the optimal controller and the state observer were designed by using the optimal control theory and the manner of pole configuration. The invariable depth-variable speed process and invariable speed-variable depth process of the thermal power system with optimal regulator were simulated. The simulation result indicates that the designed optimal regulator can gain ideal control quality, the performance of the system was improved.
