An energy-efficient and simple method of testing electric motors in a dynamic mode is considered. When testing an electrical machine, the rotor is driven into a reciprocating rotary motion. The source of power of the power converter, which controls the electric machine, is a supercapacitor. When the electric machine is accelerated, electric energy is consumed from the supercapacitor, when the machine brakes the kinetic energy of the moving masses is converted into electrical energy, which accumulates in the supercapacitor. The energy loss during the operation of the electromechanical system in the dynamic mode is compensated by recharging the supercapacitor using a controlled rectifier connected to the power supply network.

Effect of friction on the motion control processes in mechatronic systems is considered. The analysis of modern friction modeling methods is carried out. Features of processes at low speeds: accuracy, oscillations and stability have been studied on base of macroscopic models of friction. Friction in the mechatronic system causes the formation of complex nonlinear speed feedback, which depends on many factors and has different signs at different speeds. Oscillations and a violation of the stability of the system are possible with positive feedback at low speed. The conditions of stable operation under frictional load for a DC motor are derived. Correction methods for mechatronic systems with friction are considered. Effective control in mechatronic systems achieve using the principle of subordinate coordinate control. The results of modeling systems with the main feedback on the angular speed and angle of rotation are presented.
