摘要
针对单元机组协调控制对象的非线性、时变和纯迟延的特点,在Smith预测控制的基础上引入了模糊自整定方案,提出了一种单元机组协调控制设计的方法。对某500MW单元机组进行仿真试验,结果表明:这种新的控制方案不仅具有满意的控制性能,而且具有较强鲁棒性和抗干扰性能,它显著提高了协调控制系统在机组负荷工况变化时的适应性和控制品质。
According to the performance of fossil fuel-fired units, a new method for the design of unit coordinated control system is suggested. The scheme of fuzzy self-adjust based on the Smith predict control is introduced. The simulation results show that this design is feasible.
