Among routine three impulse control system, because reason of " false liquid location" make steam load rise and drop dynamic characteristic when curve asymmetric, degeneration, can't ask out the accurate mathematics model when and there are the systematic parameters, can't design the accurate feedforward controller either, can only realize the static feedforward , can realize that there is not error in the stable state , but does not control dynamic performance well.

而在常规的三冲量控制系统中，由于&虚假液位&的原因使得蒸汽负荷上升和下降时的动态特性曲线不对称，且系统参数具有时变性，不能求出准确的数学模型，也就不能设计出准确的前馈控制器，只能实现静态前馈，能实现稳态无误差，但对动态性能控制不好。
