摘　　要：核电厂蒸汽发生器(SG)水位存在"收缩"与"膨胀"的逆动力学效应、随运行功率而变化的动力学特性,对其水位控制系统在各种工况下的调节品质要求较高。本研究基于静态H∞-回路成形方法设计SG水位的鲁棒比例积分微分(PID)控制器。仿真结果证实该方法所设计的鲁棒PID控制器的有效性优于其他3种基于H∞-回路成形方法设计的控制器,所得的鲁棒PID控制器具有良好的给定值跟踪、抗干扰性能,并能在负荷变化的情况下保持较好的控制能力。The problem for control of steam generator water level is complex because its complicated shrink and parameters of its model vary with operation conditions. Static H∞loop shaping is used to design the robust PID controller for the steam generator. Simulation results show that the control efficiency of this scheme is better than that of the other three H∞ loop shaping based methods, and the derived controller has good reference tracking capability, distribution rejection ability and acceptable control performance at different operation points.
