Design and stability enhancement of a smart controller for adaptive educational management, inspired by piezoelectric sensor-actuator plates

We will create a smart controller for educational management systems to optimize their design and stability. This will include inspiration from more advanced structures such as piezoelectric sensor-actuator plate systems. In particular, we will utilize a GNP (graphene nanoplatelet) reinforced core system to achieve high performance, resilient behaviors similar to those found in smart composite materials. To develop a mechanical model of the system, we will employ the Halpin-Tsai model to determine effective material properties and higher order shear deformation theory to properly capture transverse shear effects and improve the fidelity of our model. Next, we will derive the governing equations for the system using Hamilton's principle through virtual displacements based on the Green-Gauss theorem to ensure that we have mathematically solid foundations for our models. Additionally, we will implement a state dependent damping control strategy for increased system stability and response time under different operating conditions; allowing for continued real-time adjustments to system parameters similar to what is seen with piezoelectric sensor-actuator systems' dynamic feedback mechanisms. The Laplace transform is used to study the dynamics of a system and its stability with the time-domain solutions calculated numerically via the modified Dubner and Abate algorithm. When applied, our proposed model achieves increased stability margins, improved convergence rates, and better disturbance resistance than traditional control systems. Our results suggest that bio-inspired smart material concepts would dramatically enhance the adaptability and performance of educational management control systems. As such, this project represents an interdisciplinary effort to link the mechanics of nanocomposites with the design of intelligent control systems, providing a new approach to the development of resilient and adaptive frameworks for managing complex, data-rich educational markets.
