SUMMARY
Features of development models and modeling of stabilization systems of ground vehicle equipment are considered. Features of the optimal synthesis procedure for the system of the considered type are mentioned. The main goal of the research is to study the design features of the stabilization system with the digital control unit. Two approaches to the discretization of a system with the digital control unit are given. Appropriate block-diagrams are represented. Analysis of sampling methods and appropriate software is given. Possible program realizations of transfer functions in a model of the digital control unit are discussed. Features of representation of digital filters unit are proposed. Modelling of the stabilization system with the digital control unit was carried out. Simulation results are represented. Transient processes on the angular rate with different ways of sampling are given. Results of the comparative analysis of different sampling ways are shown in the tabular form. The obtained results can be useful for designing control systems of the wide type.
