“…The relevance of the transition process analysis in the course of switching in electrical circuits is beyond any doubt since today high-speed switching devices are more and more often used in power supply systems: vacuum and gas-operated switches, magnetic starters (mostly applied in electric drive systems to control asynchronous motors) [9].…”

The research work considers the simulation and analysis of transition processes in linear electrical circuits using the MatLab software package. The transition processes occurring in the following linear electrical circuits were analyzed: RL equivalent circuit in case of connecting the relay control winding to a DC voltage source; RC equivalent circuit in case of connecting a capacitor through a limiting resistor to a DC voltage source and disconnecting it from the source; RLC equivalent circuit in case of capacitor discharge to an inductor; this capacitor shall be pre-charged from a DC voltage source; a branched electrical circuit of the first order where its topology changes after switching. As a result of the research, the transition process graphs were obtained for which the simulated completion time of the transient process does not differ from the calculated values with an error of less than 2%. The analysis of transition processes revealed the following: the winding inductance effect on the time of relay switching; the effect of the additional resistance value on the charge (discharge) of the capacitor; the effect of the resistance value change when the capacitor is discharged in a circuit with two reactive elements; the effect of changes in the topology of the electrical circuit on the intensity of the transient process after switching.

The paper considers the peculiarities of linear system simulation in the MatLab software package using the structural blocks of the Simulink application. Typical links of linear systems and their transfer functions are described. The simulation process is exemplified by the system of the object control by its rotation angle. A structural diagram is built for such a system, the mathematical model of which is made in the form of an aperiodic link of the first order. The parameters of the controllers forming the control signal are calculated. A detailed description of the model construction is provided in the Simulink application of the MatLab software package. As a result of simulation, the authors obtained the graphs during the study of the object control system: 1) under external impact without changing controller parameters; 2) under external impact when using a PID controller. The final model was built; it allows comparing the curves of the object rotation control signal in the system with the PD controller and the PID controller as well as displaying the transient curves of the object rotation angle.
