| 摘 要： | 针对主汽温系统大惯性、非线性的特点,提出了基于状态变量多模型的控制方案,即先采用状态反馈补偿主汽温系统的惯性,同时调整状态反馈系数矩阵,使得补偿后被控对象开环稳态增益稳定不变;再针对不同工况下对象特性的变化,对各工况控制子系统进行模态综合,以PID作为控制器,实现大范围控制.对主汽温系统的仿真结果表明,该方案可以较好地解决系统的大惯性和非线性问题.

| Abstract: | In the modern thermal power plant,the superheated steam temperature is one of the main parameters of the boiler,which is very important for unit safety.Aiming at the characteristics of large inertia and non-linearity,the main steam temperature system is controlled using state variable and multi-model.State feedback is used to compensate the large inertia.Then adjust state feedback matrix to make the gain of the compensated plant stable.The feature parameters of main steam temperature system are different in... |
