番茄酱一效发酵罐建模及控制仿真

An Effective Fermentation Tank Modeling and Control Simulation to the Ketchup

针对番茄酱一效发酵罐内番茄酱液面高度和罐内温度的动态控制,建立了番茄酱输入质量同罐内剩余质量、输出质量及蒸汽输入热量与发酵罐系统热量相平衡的数学模型,并在Matlab中采用粒子群优化算法对番茄酱输入质量和蒸汽量系统进行优化控制仿真。仿真结果表明,采用粒子群优化算法能够将罐内液面高度和温度控制在所要求范围内,且该算法控制速度快、精度高、工作量小,能够提高生产率,对实际生产过程具有十分重要的指导意义。

In order to control the liquid level of ketchup and temperature in the fermentation tank, a mathematical model, that the input mass is balanced with the residual mass and the output mass, as well as the input steam heat with the heat of fermen-tation tank system, is established in this paper. Besides, this model is simulated in the Matlab by using the PSO algorithm. The simulation result indicates that the range of liquid level and temperature can be controlled by using the PSO algorithm. Such algorithm has advantages of fast control speed, high precision and small work-load, so it has very important guiding sig-nificance in practical production process.
