摘　　要：针对低温多效蒸馏(LT-MED)海水淡化系统中冷凝器出口海水温度控制问题,在蝴蝶优化算法(BOA)的基础上,提出了一种改进BOA-PID控制方法,并利用MATLAB软件搭建仿真模型,将改进BOAPID控制的控制效果与BOA-PID控制、常规PID控制进行对比。结果表明,改进BOA-PID在适应度值和全局搜索能力方面表现卓越;与常规PID控制相比,基于改进BOA-PID控制系统中相应的优化程序能够自动整定各个参数,提升了系统的响应速度,大幅减小了超调量,提升了海水淡化系统的造水比,系统能正常运行。A modified BOA-PID control method is proposed based on the butterfly optimization algorithm(BOA)to address the temperature control problem at the outlet of the condenser in the low temperature-multi effect distillation(LT-MED)seawater desalination system.A simulation model is constructed using MATLAB software to compare the control effect of the improved BOA-PID control with BOA-PID control and conventional PID control.The results show that the improved BOA-PID performs excellently in terms of fitness values and global search ability;compared with conventional PID control,the corresponding optimization program in the improved BOA-PID control system can automatically adjust various parameters,improve the response speed of the system,significantly reduce overshoot,improve the water production ratio of the seawater desalination system,and enable the system to operate normally.
