Proposed Modification

Purpose of this work is to of the research – Increasing the sensitivity of a method for diagnosing phase synchronization of autogenerators based on their non-stationary time series in real time, and also a comparison of the statistical properties of the proposed modification of the method with the well-known method for diagnostics of loop synchronization, which has proven itself in the analysis of experimental data. Methods.The paper compares the probabilities of the appearance of an error of the second kind of the developed modified method for diagnostics of phase synchronization with the probabilities of occurrence of an error of the second kind of the known method at equal values of sensitivity. When comparing the methods, generated test time realizations with a priori known boundaries of the phase synchronization sections are used, which repeat the statistical properties of the experimental data. It also compares the computational complexity of the two methods. Results. A modification of the method for diagnosing phase synchronization of autonomic regulation circuits in real time is proposed. It is shown that the proposed modification provides similar values of sensitivity and probability of appearance of errors of the second kind as the previously proposed approach. The developed method has less computational complexity than the previously proposed method. The values of free parameters corresponding to different values of sensitivity and probability of appearance of errors of the second kind are obtained. Conclusion. The area of application of the developed method with modification is formulated. The low computational complexity of the proposed method, as well as the possibility of switching devices to integer computations in calculations, makes it possible to use it for wearable registrations performing calculations in real time, based on small-sized low-power processors that do not support floating-point arithmetic operations.

Autonomous Objects

An adaptive phase-locked loop is considered, which makes it possible to improve the stability of synchronous active filters, to achieve compensation for high-quality harmonic components of the current consumed by autonomous objects. Therefore, the use of such an active filter will improve the power quality and the normal trouble-free operation of the equipment in general. A control system with an adaptive phase-locked loop often has the advantages of a reliable and efficient control system. It makes it possible to quickly respond to dynamic changes in the load, which is typical for the operation of functional equipment of autonomous objects. The control system becomes more flexible, reliable, efficient and provides an instantaneous value of the compensation current from the measured values of the load current curve. Calculations can be carried out in real time. LMS, NLMS, RLS algorithms are considered as adjusting the weighted adaptive phase-locked loop in the system for correcting the supply voltage parameters. Based on the simulation of algorithms carried out in the MATLAB environment, a comparative analysis of their effectiveness is made. It is shown that the NLMS algorithm has the highest suppression quality and minimum transient time. The NLMS algorithm works in real time and is recommended for use in the supply voltage correction system.

Rate Frequency

In this study, we investigate the influence of musical tempo on the heart rate. Previous studies showed ambiguous results. Two effects are considered: first, an adaption of the heart rate frequency to the tempo of a musical stimulus (‘entrainment’) and second, the phase synchronization between the stimulus-onset and the R-waves in the ECG (‘synchronization’). A regulatory feedback loop was programmed, which constantly measured the actual heart rate. A simple Djembé-beat was used as a musical stimulus and coupled to the actual heart rate in real-time. To test for ‘entrainment’ effects, we adapted the tempo of the stimulus in real-time to the actual heart rate by increasing the rate 25%, 40% or 55% over the baseline tempo. To test for ‘synchronization’ effects, we presented the stimulus in a constant tempo, tracking the actual heart rate of the test person. Based on circular statistics, results showed no evidence for ‘entrainment’ or ‘synchronization’ effects of the stimulus on the heart rate. Overall, reactions to the trigger pulse were characterized by a high degree of interindividual differences. Thus, we conclude that there is no direct and simple correlation between the musical tempo and the HR contrary to what is often suggested in everyday psychology.

Numerical simulations and experimental measurements performed on a plasma discharge, simultaneously paced with two independent sinusoidal functions, show the plasma moving from one synchronous state to another, back and forth, between the two independent pacers. Different approaches for studying this competition for phase synchronization indicate the relevance of the relative frequency values of the two sinusoidal functions with respect to the predominant frequency characteristic of the unpaced plasma discharge.

As a set of protocol standards defining time sensitive mechanism of Ethernet data transmission, Time sensitive network (TSN) can support transmission of isochronous data and non-periodic data in the same network . Distributed synchronous control plays an important role in large precision manufacturing scene. In this paper, a distributed real-time synchronous motion control scheme of two motors based on TSN is proposed, and the experiment shows that the two motors moving at high speed can still maintain phase synchronization under the scheduling mechanism of IEEE Std 802.1Qbv even if there is a large traffic load in the network.
