在对火电厂过热汽温控制对象特点分析基础上 ,保留串级控制抗内扰的性能 ,结合模糊控制动态特性好的特点 ,提出了一种复合模糊串级控制设计。仿真结果表明 ,用这种方法建立的过热汽温控制系统具有较好的控制品质和抗干扰能力。
Based on the analysis of the characteristics of superheated steam temperature control object in thermal power plant, the performance of cascade control anti-jamming is retained. Combined with the good dynamic characteristics of fuzzy control, a hybrid fuzzy cascade control design is proposed. The simulation results show that the superheated steam temperature control system established by this method has better control quality and anti-interference ability.
