Study on PID Control System Based on Genetic Algorithms

摘要：

　　As for the characteristics of hysteretic,nonlinear and time-varying after aeration process,the control of the dissolved oxygen concentration DO is as the mathematical model object,with the use of fuzzy PDI control strategy through the comparison among the MATLAB simulation,PDI control and the applicable results for the conventional fuzzy control strategy.Because the fuzzy control parameters of the fixed PDI cant be guaranteed various conditions on the control effect of DO,thus,genetic algorithms cant be automatically optimized several key parameters to design the fuzzy PDI control:the membership function,rule table of fuzzy control and the scale factor,then MATLAB simulation is carried out,with the comparison among the PDI control based on genetic algorithms,conventional fuzzy control strategy and the simulation results.
