Study on PID Parameter Optimization Based on GA Toolbox of MATLAB

Genetic algorithm is the search algorithm with robustness. It Can be used for optimization of complex systems. Genetic algorithm optimization toolbox (GAOT) provides a good tool for the popularization and application of genetic algorithm. In view of the limitation of conventional methods,a method for PID optimization using GAOT is researched in this paper. The simulation result shows that the system using the method based on GAOT is of no overshoot. As well,the settle time are shorter. The better control effect than the traditional design methods was get by this method.
