积分切除法在核电厂控制系统中的应用分析

Analysis of Anti-Windup Technique in NPP Control Systems

针对控制系统最常用的比例积分微分(PID)控制中的积分饱和问题,提出了基于积分切除法的3种控制算法,并将3种算法应用于核电厂稳压器压力及蒸汽向大气排放系统中。仿真结果表明,对不同的控制系统选用适当积分切除算法后,在满足系统功能要求的同时可以有效避免系统因饱和作用带来的不利影响。

Concerning the problem of integral saturation in PID control which is commonly used in the control system, three algorithms of the anti-windup method are raised and applied to pressurizer pressure and steam dump to the atmosphere control systems. The simulation result shows that with making appropriate application of the anti-windup algorithm to different control systems, the requirement of system function can be met and the adverse effect caused by saturation can be avoided effectively. © 2015, Editorial Office of Nuclear Power Engineering.
