基于数字调节器的稳压器压力控制系统,同时针对稳压器升、降压的不同动态特性,设计具有2组调节器参数的数字调节器控制系统,并给出含自动切换功能的控制策略SAMA图设计。最后,在SIMULINK仿真软件平台里实现调节器的2组比例积分(PI)参数整定。仿真结果验证此设计可以更好地将压力控制到稳定值,提高核电厂运行的安全性。
Based on the digital regulator regulator control system, aiming at the different dynamic characteristics of the regulator, the digital regulator control system with two sets of regulator parameters is designed and the control strategy with automatic switching function is given SAMA diagram design. Finally, two sets of proportional integral (PI) tuning of the regulator are implemented in the SIMULINK simulation software platform. Simulation results verify that this design can better control the pressure to a stable value and improve the safety of nuclear power plant operation.
