We know that the superheated steam temperature of boiler superheated system in the fired power plant has nonlinear, uncertain, large time-delay and large inertial characteristics.
我们知道，火电厂锅炉高温过热器的过热汽温是一类非线性、时变大、大时滞、大惯性的典型对象。
But because the system has the characters of inertial delay, nonlinearity, time-varying, it is difficult to construct its accurate mathematical model.
但由于系统存在惯性滞后、非线性、时变等特点，采用传统的控制理论无法取得理想的控制品质。
