摘要
黄酒发酵溶氧控制系统是一个多干扰的、时变的、非线性的不稳定系统。提出了一种新的黄酒发酵溶氧控制方法,在Labview组态软件、西门子PLC300和溶氧传感器所组成的溶氧系统上,引入卡尔曼滤波遗传PID控制策略,实现溶氧PID控制参数的在线整定。应用卡尔曼滤波减小控制干扰和测量噪声对系统造成的影响,并用Matlab进行仿真实验。仿真结果表明,该控制方法对被控对象的适应性好,抗干扰能力强,具有较强的鲁棒性和较快的收敛速度。
The Dissolved Oxygen（DO） control system for rice wine fermentation is an unstable system with multi-disturbance,time-varying and nonlinearity.A novel DO control method is proposed.The system is based on Labview,SIMATIC PLC300 and sensors,the Kalman filtering and Genetic PID control strategy are introduced.The PID control parameters are tuned by genetic algorithm on line,while a Kalman filter is used to reduce the impact of control interference and noise on system.Finally,a simulation experiment is performed by Matlab,and simulation result shows that the control method not only has a good adaptability and Anti-disturbance but also has strong robust ability and fast convergent rate.
