摘　　要：在环保要求日渐严格的大工业时代背景下,提升有色金属火法冶炼自动控制水平从而改善其能源利用效率符合国家政策要求和企业自身利益,也是本研究的方法与最终目标。针对有色冶炼厂电力分厂机炉协调控制能力有限甚至缺乏协调控制设计的现状,提出以大型锅炉作为蒸汽补充来源并设计了协调优化控制策略,分别研究了采用传统PID解耦控制器方案、模糊控制器方案、模糊PID控制器方案和单神经元自适应控制器方案的特点。在此基础上进一步提出将模糊控制器与传统PID控制器并联,在被调量接近目标值时,根据经验降低控制作用以减小超调和调节时间即实现模糊柔化控制。仿真结果表明,所设计的协调优化控制策略及并行模糊优化控制器与常规方案相比,在控制精度与响应速度等方面更具优势,对现场实际生产具有一定的指导意义。In the context of an industrial era where environmental protection requirements are becoming increasingly stringent,improving the level of automatic control of nonferrous metals pyrometallurgy and thus its energy efficiency is in line with national policy needs and the interests of the companies themselves.In addition,this is the approach and ultimate goal of this study.In response to the current situation of limited or even lack of coordinated control design of the boiler and turbine in the power branch of a nonferrous smelter,a large boiler is proposed as a supplementary source of steam,and a coordinated and optimized control strategy is designed.The characteristics of using the traditional PID decoupling controller scheme,the fuzzy controller scheme,the fuzzy PID controller scheme and the single neuron adaptive controller scheme are investigated respectively.On this basis,it is further pro-posed to parallel the fuzzy controller with the traditional PID controller.The control action is empirically reduced to reduce overshoot and regulation time when the regulated quantity is close to the target value i.e.to achieve fuzzy softening control.Simulation results demonstrate that the designed coordinated optimized control strategy and parallel fuzzy optimized controller have advantages over conventional schemes in terms of control accuracy and response speed,providing some practical guidance for the field.
