摘　　要：针对传统PID算法对于低温多效海水淡化(LT-MED)温度系统中存在的大惯性、大时滞环节的控制无法达到理想效果的问题,本文基于线性自抗扰控制(LADRC)算法,设计了低温多效蒸馏海水淡化温度系统控制器,利用SIMULINK仿真平台将其与基于传统PID算法的控制器进行控制效果比对.仿真结果表明,本文使用的线性自抗扰控制器(LADRC)用于该系统的温度控制,相比传统PID方法效果更佳.In view of the problem that the traditional PID algorithm can not achieve the ideal effect for the control of large inertia and large time delay in the temperature system of low-temperature multi-effect seawater desalination(LT-MED), this paper designs the temperature system controller of low-temperature multi-effect distillation seawater desalination based on Linear Active Disturbance Rejection Control(LADRC) algorithm. SIMULINK simulation platform is used to compare its control effect with the controller based on the traditional PID algorithm. The simulation results show that the LADRC used in this paper is better than the traditional PID method in temperature control of the system.
