Multiple-Models Adaptive Disturbance Observer-Based Predictive Control for Linear Permanent-Magnet Synchronous Motor Vector Drive.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Power Electronics. Aug2022, Vol. 37 Issue 8, p9596-9611. 16p.

Abstract: To achieve high-performance control of the precise linear permanent-magnet synchronous motor (LPMSM) control system, a composite robust current regulation method with good dynamic response and disturbance rejection performance is proposed. First, a con...

The Grid Bootstrap for Continuous Time Models.

Publication Type: Academic Journal

Source(s): Journal of Business & Economic Statistics. Jul2022, Vol. 40 Issue 3, p1390-1402. 13p.

Abstract: This article proposes the new grid bootstrap to construct confidence intervals (CI) for the persistence parameter in a class of continuous-time models. It is different from the standard grid bootstrap of Hansen in dealing with the initial condition. Th...

Dynamics and analysis of a mathematical model of neuroblastoma treated with Celyvir.

Publication Type: Academic Journal

Source(s): Applied Mathematical Modelling. Oct2022, Vol. 110, p131-148. 18p.

Abstract: • We develop two mathematical models to account for tumor-inmune cell interaction with Celyvir therapy. • We study the stability analysis for both models and we find bifurcations depending of the parameters. • For the second model, we use impulsive dif...

Surplus production models: a practical review of recent approaches.

Publication Type: Academic Journal

Source(s): Reviews in Fish Biology & Fisheries. Dec2022, Vol. 32 Issue 4, p1085-1102. 18p.

Abstract: Increasing the knowledge of approaches to estimate the status of data-limited stocks is of crucial importance since the vast majority of stocks are data-limited, i.e., there is not enough data to conduct a fully integrated statistical catch-at-age or a...

Modelling and stability analysis of a longitudinal wheel dynamics control loop with feedback delay.

Publication Type: Academic Journal

Source(s): Vehicle System Dynamics. Nov2022, Vol. 60 Issue 11, p3765-3787. 23p.

Abstract: Vehicle safety is an important field of today's engineering practice and the scientific research as well. One of the basics of the modern vehicle system dynamics control systems is braking or driving torque control. Ensuring proper connection between t...

Adaptive efficient estimation for generalized semi-Markov big data models.

Publication Type: Academic Journal

Source(s): Annals of the Institute of Statistical Mathematics. Oct2022, Vol. 74 Issue 5, p925-955. 31p.

Abstract: In this paper we study generalized semi-Markov high dimension regression models in continuous time, observed at fixed discrete time moments. The generalized semi-Markov process has dependent jumps and, therefore, it is an extension of the semi-Markov r...

Simplifying the interpretation of continuous time models for spatio-temporal networks.

Publication Type: Academic Journal

Source(s): Journal of Geographical Systems. Apr2022, Vol. 24 Issue 2, p171-198. 28p.

Abstract: Autoregressive and moving average models for temporally dynamic networks treat time as a series of discrete steps which assumes even intervals between data measurements and can introduce bias if this assumption is not met. Using real and simulated data...

Long-term concentration of measure and cut-off.

Publication Type: Academic Journal

Source(s): Stochastic Processes & Their Applications. Oct2022, Vol. 152, p378-423. 46p.

Abstract: We present new concentration of measure inequalities for Markov chains, generalising results for chains that are contracting in Wasserstein distance. These are particularly suited to establishing the cut-off phenomenon for suitable chains. We apply our...

On some relations between a continuous time Luenberger productivity indicator and the Solow model.

Publication Type: Academic Journal

Source(s): Bulletin of Economic Research. Apr2022, Vol. 74 Issue 2, p484-502. 19p. 3 Diagrams.

Abstract: We introduce well‐known microeconomics productivity measures in Solow models in discrete time or continuous time by adopting a Luenberger‐type approach. In each framework, we derive the productivity indicators and the dynamical paths. First, we show th...

DYNAMICS OF A MATHEMATICAL MODEL FOR INTERACTION PLANT–PARASITE–TRICHODERMA.

Publication Type: Academic Journal

Source(s): Journal of Biological Systems. Sep2022, Vol. 30 Issue 3, p585-603. 19p.

Abstract: In this work, the impact of a biological agent (Trichoderma spp.) on the dynamic of a plant–parasite model is analyzed. It is assumed that the plant–Trichoderma spp. relationship is mutualistic, the Trichoderma spp.–parasite relationship is that of pre...
