Identifying the mathematical model of the analog circuit through the IO data is the key technology in the model-based fast equipment test method.According to the electrical characteristics of the analog circuit system,we designed R-square-based fitness function,and the selection strategy combined with elitism and roulette.The establishment method of analog circuit system identification based on gene expression programming(GEP) was constituted with the partially mapped crossover operator,the heuristic mutation operator,and the sequence insertion operator.Compared with the MATLAB system identification toolbox,this method can identify not only the system parameter,but also the structure.If you set the suitable identification precision,we can get the theoretical system model via the SISO and MIMO tests.
