摘　　要：针对热交换器出口温度特性延迟大、偏差大、抗干扰能力差、过渡时间长的缺点,考虑到物流流量对被控对象的扰动,在传统PID控制基础上加入了前馈环节,并利用仿真软件进行了控制参数的整定及优化,仿真结果表明优化后的热交换器出口汽温控制效果有较大的提升,且克服可测干扰的能力较强。For the traditional heat exchanger outlet temperature control with long delay time,large deviation,poor an- ti-interference ability,long transition time and other shortcomings,while considering the logistics flow disturbance of controlled object,this design adds the segments of feedforward and feedback on the basis of the traditional PID con- trol, and sets parameters and optimizes control through computer simulation software. Thus, the parameters of the heat exchanger outlet temperature regulator are set and optimized. The simulation results show that the optimized heat ex- changer outlet steam temperature can achieve good control effect and can overcome strong measurable interference.
