摘　　要：臭氧有很强的氧化特性和消毒特性,在工业污水处理等领域均被广泛的应用。现今被广泛应用于工业臭氧制备领域的方式是介质阻挡放电法,此方法能够制备出高浓度的臭氧。而现在已有的臭氧发生器大都采用开环控制,无法根据实际的产量和浓度需求进行控制,因此存在能耗高且效率低的问题。采用传统的PID控制对系统进行闭环控制能够初步解决这个问题,但是要从本质上提升还需要更高端的算法,所以要在系统控制方面进行更加深入的研究。由于臭氧发生系统的放电室结构比较复杂,并且系统中影响臭氧生成的内部参数比较多,因此无法通过机理进行建模。提出了基于无模型自适应控制算法的臭氧发生系统相关研究,此算法仅需要系统的输入输出数据,排除了其他外在因素的影响。通过实验得出,无模型自适应控制算法控制效果明显优于传统的PID控制效果。Most of the existing ozone generators use open-loop control,which cannot be controlled according to the actual output and concentration requirements,so there are problems of high energy consumption and low efficiency.The closed-loop control of the system using traditional PID control can initially solve this problem,but a higher-end algorithm is needed to fundamentally improve,so more in-depth research on system control is required.Because the structure of the discharge chamber of the ozone generation system is relatively complex,and there are many internal parameters affecting ozone generation in the system,it cannot be modeled by mechanism.In this paper,a related research on ozone generation system based on model-free adaptive control algorithm is proposed.This algorithm only needs the input and output data of the system and excludes the influence of other external factors.Through experiments,it is concluded that the control effect of the model-free adaptive control algorithm is obviously better than that of the traditional PID control.
