A novel approach to design and analyze fractional order PID controller for speed control of brushless DC motor
No full textIn industries Brushless DC(BLDC) motors with conventional PID controllers which are based on linear control theory are widely used. BLDC motors often require precise speed control for various applications like robotics, electric vehicles and industrial automation etc.. The recent advancement in Fractional order calculus in control theory is also seeking attention of researchers because of certain advantages over conventional controllers. In comparison with conventional controlling of Brushless DC motor, Fractional Order PID (FOPID) controllers outperforms in terms of better dealing with the variable time delays, varying plant parameters, nonlinearity and considerable plant noise. This research paper compares conventional and fractional order control and offers a novel method for designing a fractional order PID controller for BLDC motors. Overall, it is noticed that the novelty of FOPID lies in its ability to leverage fractional-order dynamics to achieve improved control performance, enhanced adaptability, and better robustness as compared to traditional Ziegler Nichols method based PID controllers. The proposed models of Fractional Order PID-based control of Brushless DC motors are designed and validated in MATLAB with the help of FOMCON toolbox.

Leadership and Quality of Life: Navigating Health Systems Through Crisis Management and Beyond of Life in Chronic Disease Management
No full textIntroduction: This article focuses on the leadership in health systems in crisis and its effect on the quality of life. It essentially covers how good leadership can steer through extraordinary times like now, during the COVID-19 pandemic, and make way for quality care delivery and better population health outcomes in the future.Methods: The study uses a systematic review methodology to collect and analyse literature on leadership and health systems, crisis management and quality of life. This SCOPUS and PUBMED systematic review was based on 50 articles selected for analysis through a rigorous evaluation of relevance and evidence quality.Results: We now know that leadership is the most important factor in navigating crises as well as the responder systems more generally striving to enhance life among the communities they serve. By having a clear vision, pragmatic communication and adaptability, leaders can steer their teams and organizations through volatile periods and come out with better results. Moreover, good leadership is also important for building public trust and confidence during crises, which is important to increase the level of compliance with public health measures.Conclusions: To conclude this paper, we have emphasised the vital impact of leadership on the quality of life within health systems and at all organisational levels, especially during times of crisis. It highlights the importance of leaders having the skills and qualities needed to successfully manage and navigate through extraordinary circumstances and improve overall population health outcomes. Moreover, additional studies are needed to identify the particular leadership attributes, approaches, and styles that best serve us in addressing health system crises and enhancing quality of life.Introducción: este artículo se centra en el liderazgo en los sistemas sanitarios en crisis y su efecto en la calidad de vida. Esencialmente, trata de cómo un buen liderazgo puede dirigir en tiempos extraordinarios como los actuales, durante la pandemia de covid-19, y abrir paso a una prestación asistencial de calidad y a mejores resultados de salud de la población en el futuro.Método: el estudio utiliza una metodología de revisión sistemática para recopilar y analizar bibliografía sobre liderazgo y sistemas sanitarios, gestión de crisis y calidad de vida. Esta revisión sistemática de SCOPUS y PUBMED se basó en 50 artículos seleccionados para su análisis mediante una evaluación rigurosa de la pertinencia y la calidad de las pruebas. Resultados: ahora sabemos que el liderazgo es el factor más importante en la navegación de las crisis, así como los sistemas de respuesta más en general que se esfuerzan por mejorar la vida entre las comunidades a las que sirven. Al tener una visión clara, una comunicación pragmática y capacidad de adaptación, los líderes pueden conducir a sus equipos y organizaciones a través de periodos volátiles y salir con mejores resultados. Además, un buen liderazgo también es importante para fomentar la confianza del público durante las crisis, lo que es importante para aumentar el nivel de cumplimiento de las medidas de salud pública.Conclusiones: para concluir este documento, hemos hecho hincapié en el impacto vital del liderazgo en la calidad de vida dentro de los sistemas sanitarios y en todos los niveles organizativos, especialmente en tiempos de crisis. Se destaca la importancia de que los líderes posean las habilidades y cualidades necesarias para gestionar y navegar con éxito a través de circunstancias extraordinarias y mejorar los resultados generales de salud de la población. Además, se necesitan más estudios para identificar los atributos, enfoques y estilos de liderazgo concretos que mejor nos sirven para afrontar las crisis de los sistemas de salud y mejorar la calidad de vida
Performance assessment of network system network comprising four subsystems via multi failure and multi repair methodology
No full textA multi-dimensional repair approach is the most effective policy for restoring repairable systems. This research study analyzes a complex repairable system that consists of four subsystems with different configurations. The system consists of four subsystems: Subsystem 1 contains a single unit, Subsystem 2 includes n identical units operating under a k-out-of-n: G policy, Subsystem 3 features two identical load balancers responsible for distributing the load (with at least one required for operation), and Subsystem 4 consists of four identical units functioning under a 3-out-of-4: G policy. It is assumed that all subsystems have constant failure rates that are distributed exponentially. General repair, which is utilized while the system continues to function in accordance with the established operating policy, and copula-based repair, which is employed when the system stops completely, are the two types of repair techniques that are put into practice. A supplementary variable approach is incorporated to analyses system performance. Various reliability measures are computed using Maple 18, software, and future behaviour of system have been predicted in long run operation. By means of illustrations in the tables and graph it clearly shown how the copula repair is beneficial over ordinary repair
