Application of the genetic algorithm and simulated annealing to LC filter tuning

The paper discusses and compares the application of genetic algorithm and simulated annealing methods to LC filter tuning. Specifically, the paper is concerned with the application and implementation of these methods for the development of a fast microprocessor-based automatic antenna tuning unit, providing the facility to adapt to changes in load impedance, temperature or environment, A number of simulations were carried out to evaluate the relative performance of these algorithms. Finally, experimental results are presented where the simulated annealing algorithm was used to control a commercial impedance matching device in real time.
