The article solves the problem of developing an intelligent system for controlling the process of aluminum waveguide paths induction soldering. The authors introduce a concept of a control system, within the framework of which the use of fuzzy logic methods is suggested as a solution. A generalized scheme of an intelligent automated induction soldering system is constructed that forms control based on a mismatch between the temperatures and heating rates of the welded waveguide assemblies, as well as the evaluation of the soldering process control quality on the basis of temperatures and heating rates mismatch. As the output parameters of the intelligent system, the choice of the control algorithm is proposed, as well as the amount of regulator coefficients correction. Based on the results of the expert evaluation, the terms of the input and output variables are composed. The proposed control algorithm is implemented within the framework of the current automated control system for spacecraft’s waveguide soldering. Based on the results of numerical experiments, both the forms of control actions in the system and their parameters were selected. The proposed approach to the formation of control was tested in a series of full-scale experiments on the waveguide paths soldering, as a result of which the heating curves of the product elements were obtained, according to which it is possible to judge the effectiveness of using intelligent control based on a fuzzy regulator. Application of the proposed approach allows ensuring high quality of induction heating process control and obtaining reliable permanent connections of waveguide path elements.
