The Study Of Simulation Of Control System Based On Genetic Algorithms

In the dissertation PID-control system is analyzed and simulated using Matlab as a tool of data processing. Genetic algorithm is used to search for the best PID factors. GA is a global optimization algorithms with high robust performance．It has been widely applied in automatic control field．PID optimization based on GA realizes the multi－objective optimization of time domain and frequency domain performance targets. Form the simulation result,we can see GA is a good method to select PID factors, and has its theoreticism and actuality.The most applications of the GA in the automatic field are still in theoretical simulation．This dissertation presents a data communication mode between the simulative and actual systems,which uses the Matlab Engine, virtual instrument platform Labwindows/CVI, and KMM(the simulative plant), This mode presents a new method to apply e GA in the engineering to develop industrial control systems．This method is easy and intuitionistic,and valuable for engineering application．...
