The paper considers the synthesis of a non-stationary automatic control system for braking the wheels of a heavy vehicle using the generalized Galerkin method. The research method under consideration is used to solve the problem of synthesizing a non-stationary system whose desired program motion is specified at the output of a nonlinear element. The paper presents the results of studying the impact of non-stationarity on the parameters of the fixed part of the system (object) on the deterioration of the quality of the transient process. For critical operating conditions, the parameters of the controller were recalculated, and the results of accounting for non-stationarity and re-synthesis were evaluated.

Keywords: automatic control system, regulator, braking system, unsteadiness of parameters, generalized Galerkin method

The paper presents the application of the electron commutation method to solve the problem of synthesizing systems whose parameters can be functions of time. Parametric synthesis is carried out using the generalized Galerkin method extended to a new class of nonstationary systems. An impulse system of automatic control of a turbine unit is considered as an object of study at nonstationarity of parameters of the unchanged part of the system. Modeling is performed in Matlab/Simulink system.
