摘要：Proportional–integral-derivative (PID) controllers tuning is a challenging aspect for researchers and process operators. This paper proposes PID controller tuning of a three tank level process using genetic algorithm. Genetic algorithms are based on the principle of genetics and evolution and stand up as a powerful tool for solving search and optimization problems. Selection, crossover and mutation are three basic genetic operators for functioning of the algorithm. Optimization of PID parameters is evaluated using genetic algorithm with various performance indices i.e. ISE, ITAE, IAE and IME. Also the responses of three tank level process using genetic PID controller with various performance indices are analyzed and compared. Analysis is performed through computer simulation using Matlab/Simulink toolbox. The comparative study shows that the application of genetic algorithm based PID controller with ISE index gives the best performance compared to other indices for three tank level process
