Frequency-Time Domain Study of Dynamic Response of Electromechanical System with Distributed Parameters Based on Approximation Algorithm
In this paper,an experimental study of the electromechanical system with distributed parameters of the mechanical part is carried out in the frequency-time domain.The paper emphasizes the importance of considering the distribution of the parameters and analyzes the essential elements that affect their distri-bution characteristics.The experimental setup was developed during the validation phase,and the Strim-Server and CANMonitor programs were used for data acquisition and analysis;the control system was also developed,describing the process of creating the simplest calibration setup,highlighting the programming environment used to develop the control program and providing a set of programs for programming the con-troller.The effectiveness of the synthetic control system was demonstrated in frequency-domain experiments under conditions that simulated the behaviour of the electromechanical system.A comparison with the theo-retical calculations reveals that the maximum relative error to the actual value does not exceed 10%,con-firming the reliability of the theoretical calculations.In the time domain analysis,the current graph is plot-ted by the CANMonitor program and it is found that the current amplitude increases to 1.83 times at the resonance frequency,which is in line with what should be the case at the resonance frequency.This sheds light on understanding and designing electromechanical systems with distributed parameters.
