| Abstract: | The performance of PID controller depends on the combination of the control parameters.An improved particle swarm optimization was proposed for tuning and optimizing PID parameters,by applying interval algorithm and roulette wheel selection to the initialization of particle location.The simulation and experimental results show that,the proposed algorithm can overcome premature phenomena,reduce the influence of random initial population,and improve the convergence precision,which means a good application pro... |
