【Abstract】 Tuning parameters for controllers is one of the crucial issues in control engineering. To avoid the model dependence of tuning formulae and the premature convergence of genetic algorithm,and to improve optimizing and controlling performances,an effective hybrid strategy for tuning parameters is proposed which reasonably combining the parallel structure of genetic algorithm with the controllable jumping property of simulated annealing. Furthermore,the controller for water turbine system is well tuned by hybrid strategy and good performances are achieved.更多还原
