基于改进粒子群PID黄酒发酵溶解氧浓度控制

针对黄酒发酵溶氧控制时变性、非线性的特点,基于黄酒溶氧控制数学模型为二阶滞后模型的特点,提出一种单一参数寻优的改进粒子群PID控制器。仿真结果表明,提出的方法设计的PID控制器在控制黄酒发酵溶氧过程中可以有效地减少系统的调节时间和超调。

Rice Wine Fermentation DO Control Based on Improved PSO-PID

The rice DO control has a characteristic of with time-varying and nonlinearity.Because the mathematic model of the rice wine can be described as a second-order plus dead time model,this paper proposes an improved particle swarm optimization PID controller based on the single parameter optimization.The simulation result shows that the PID controller by the proposed tuning method can reduce the system settling time and the overshoot during the process of rice wine DO control.
