摘　　要：为了解决高寒地区生物氧化预处理多级氧化槽温度调节差异较大的问题,通过对单一氧化槽换热管电动调节阀使用PSO优化的PID神经网络控制方法来保障氧化槽温度控制的准确性。在此基础上,对多级氧化槽系统采用基于最大误差的速度动态补偿协同控制方法,建立速度动态补偿协同控制模型,并对其进行模拟仿真。结果表明,该方法能够精确控制多级氧化槽的温度,满足高寒地区特殊气象条件下的工艺要求。研究结果可为高寒地区生物冶金工艺的精准控制提供新的思路和方法。In order to solve the problem of large difference in the temperature regulation of the multi-stage oxidation tank in the biological oxidation pretreatment of the high cold region. PSO-optimized PID neural network control method is adopted to ensure the accurate temperature control of oxidation tank by using electric control valve of single oxidation tank heat exchange tube. On this basis, the multi-stage oxidation tank system adopts the speed error compensation control method based on the maximum error. The model of the speed dynamic compensation cooperative control method is established. The simulation results show that the method can accurately control the temperature of multi-stage oxidation tank and meet the technical requirements under the special meteorological conditions in alpine region. The research results provide new ideas and methods for the precise control of biology metallurgical process in alpine regions.
