The Optimization of PID Controller Parameters Based on Genetic Algorithms

In this paper, an optimal PID controller is designed with the Genetic Algorithms. The methods such as optimun retaining selection mechanism, double intersection at two points,individual strategy reproduction and producing primary group via simple experience formula are adopted in constructing the architecture of genetic algorithms. Simulation results illustrate the performance of the proposed method.
