| Abstract: | Genetic Algorithms is a completely new global optimum algorithm. Based on the genetic algorithms, a method is presented to identify system parameters using the improved genetic operators. With the aid of the method, unbiased parameter estimates of the system can be obtained when the output is corrupted by random noise unrelated with the input signals. The simulation results show that this method is very efficient. |
