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

The paper discusses and compares the application of genetic algorithm and s imulated 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, p roviding the facility to adapt to changes in load impedance, temperature or environment, A number of simulations were carried out to evaluate the rela tive performance of these algorithms. Finally, experimental results are pre sented where the simulated annealing algorithm was used to control a commer cial impedance matching device in real time.
