| Abstract: | Genetic algorithm is a global optimal algorithm with robustness and applicability. Genetic algorithm optimization toolbox(GAOT) provides a good tool for the popularization and application of genetic algorithm, which adopts modular designing mode and contains some common genetic operators. In view of the limitation of conventional methods, a method for PID tuning using GAOT is researched in this paper. The application steps of genetic algorithm and the principal usages of GAOT are introduced at first. Then the joint between GAOT and controller design is discussed. A simulation is carried out and the performance comparison with conventional methods such as Ziegler-Nichols method and engineering optimizing design method is made at last. Simulation results and implementation process verified its value on system implementation and system performance. |
