摘要
船用核动力装置机动性要求较高,采用直流蒸发器的船用核动力装置,多参数间具有较强的耦合关系,各主要控制器之间应能相互协调。汽轮机转速如采用常规的PID调节不能较好地满足控制需求。本文设计了汽轮机转速模糊-PID双模控制系统,并对蒸汽压力具有协调控制功能,利用模糊控制的快速动态响应和PID控制的稳态性能,来实现汽轮机转速快速跟踪、稳定控制的要求。仿真试验表明该控制系统响应时间和稳态精度都有明显改善。
The multiple parameters of the marine nuclear power plant with the once-through steam generator are strongly coupled, and the normal PID control of the turbine speed can＇t meet the control demand. This paper introduces a turbine speed Fuzzy-PID controller to coordinately control the steam pressure. The simulation shows the improvement of the response time and steady state peformance of the control system.
