Design method of automatic filter based on tribe algorithm

Abstract

The invention discloses a tribe algorithm-based design method of an automatic filter, which is characterized in that the design process of the filter is converted into a process of solving an optimal solution of a function and optimizing by using an algorithm, so that the automatic design of the filter is realized, and the optimal solution of the filter is obtained through an optimization strategy. A series of parameters of the filter are equivalent to variables in a tribe evolution mechanism, the dependence of a designer on theoretical knowledge of an electromagnetic field can be reduced, the filter with a more complex structure and more excellent performance can be designed more easily, the blindness of debugging the filter by the designer is greatly reduced, and the design efficiency is improved. The frequency of debugging the filter by a designer is reduced, and meanwhile the problem that the design precision is reduced due to the fact that the structure is simplified in the design process of the microwave filter is solved.

Problems solved by technology

[0008] The design method and design process of traditional filters are complicated, and it is difficult to achieve the optimal state of filter performance. In actual design, due to processing errors and assembly errors, the final effect of the filter often does not meet the target requirements. Error debugging in production often takes a lot of labor time and energy, and often requires very experienced engineers. Therefore, using the method of automatic filter design based on the tribal algorithm can greatly save labor costs and reduce design working hours
