Abstract：A hybrid intelligent algorithm based on genetic algorithm,ant colony algorithm and local neighborhood-search was presented to identify the parameters of a nonlinear rotor system. The merit of a quick and random searching in genetic algorithm was used into the proposed hybrid algorithm, and then pheromone distribution and search space were achieved. The merits of positive feedback, parallel processing and global searching in ant colony algorithm were utilized in the proposed hybrid algorithm. Finally the local neighborhood-search was used to achieve the exact solutions. The validity and effectiveness of the method that identify parameters of nonlinear rotor system are demonstrated by some numerical simulations.
