摘要
多效蒸发系统的控制问题较为复杂,末效出料浓度是检测产品质量的重要指标,必须确保稳定在一定范围内才能满足要求.以高蛋白饲料生产过程中的七效错流蒸发系统为例,为避免停工造成的损失及原料液浪费,针对该系统实际工况和现场数据建立其相应数学模型.在该模型基础上使用MATLAB/SIMULINK设计常规PID控制器和模糊PID控制器,对比两种算法的控制效果,验证了模糊PID控制器能够在线实时调节PID参数,更适合该多效蒸发复杂控制系统.
Abstract
The control problem of multi-effect evaporation system is more complicated.The final effect discharge con-centration is an important index to detect product quality,which must be ensured to meet the requirements within a certain range.Taking the seven-effect cross-flow evaporation system in the production of high protein feed as an example,in or-der to avoid the loss and waste of raw material liquid caused by shutdown,the corresponding mathematical model is es-tablished according to the actual working condition and field data of the system.On the basis of this model,the conven-tional PID controller and fuzzy PID controller are designed using MATLAB/SIMULINK.By comparing the control effects of the two algorithms,it is proved that the fuzzy PID controller can adjust the PID parameters online and is more suitable for the multi-effect evaporation complex control system.
