Data-Driven Modeling And Control Of A Two-Link Flexible Manipulator (Tlfm), Samuel Ayankoso May 2021

Data-Driven Modeling And Control Of A Two-Link Flexible Manipulator (Tlfm), Samuel Ayankoso

Theses and Dissertations

Two-link flexible manipulators (TLFMs) are used in different application domains, and their merits include lightweight, low energy consumption, high operational speed, transportability, maneuverability, and low cost. Despite the merits of TLFMs, the flexibility of the links introduces modeling and control problems. The existing mathematical modeling techniques of a TLFM, such as the assumed mode method (AMM), finite element method (FEM) and finite difference method (FDM are mathematically complex and do not accurately match the physical system dynamics. Lumped parameter method (LPM) model is a simplified model, but it is also inaccurate. Moreover, different forms of control problems are applicable to …


The Effect Of Learning And Cost Optimization On Line Of Balance Scheduling, Kareem Essam Zahran Jul 2014

The Effect Of Learning And Cost Optimization On Line Of Balance Scheduling, Kareem Essam Zahran

Theses and Dissertations

The increase in populations throughout the past years introduced the need for improving and increasing countries’ infrastructure. Moreover, there has been an increasing demand for dwelling units ranging from small economic housing blocks to high-rise buildings and residential villa compounds. These projects are known by their repetitive nature, where a constant unit is repeated several times. Scheduling techniques that consider the learning effect as an influencing parameter in calculating productivity rates can improve the effectiveness of the scheduling process. This achieves more realistic forecasts resulting in optimum utilization of resources and better control during implementation phases. Linear scheduling techniques are …
