Precise positioning and trajectory tracking control applications are important for industrial manufacturing and scientific research. Ball-screw, worm-gear, and power-screw driven systems are widely used for this purpose. Since power screw driven systems provide long range and allow precise servo control, they are commonly preferred. The control strategy developed for power screw driven systems is expected to be robust, to respond rapidly for fast tracking performance and to reject disturbances. These systems should also be controlled precisely in case of uncertainties. In order to enhance the overall system controllability, sliding mode control is one of the preferred strategies. In this paper, sliding mode control strategy developed for a power screw driven positioning table is introduced. Mathematical models of the power screw, positioning table and actuator subsystems are derived. An experimental positioning table setup consisting of a power screw is manufactured to which the developed controller is deployed for testing. The stability of the sliding mode controller is investigated in detail and its performance is compared to that of a PID controller for verification purposes.

Forecasting of Product Quality Through Anomaly Detection Dinç, Mehmet; Ertekin Bolelli, Şeyda; Özkan, Hadi; Meydanlı, Can; Atalay, Mehmet Volkan (2020) Forecasting of product quality by means of anomaly detection is crucial in real-world applications such as manufacturing systems. In manufacturing systems, the quality is assured through tests performed on sample units randomly chosen from a batch of manufactured units. One of the major issues is to detect defective units among the sample test units as early as possible in terms of test time and of course as accurate as possible. Traditional way of detecting defective units is to make use of human experts d...
Faux Riccati equation techniques for feedback control of nonlinear and time-varying systems Prach, Anna; Tekinalp, Ozan; Bernstein, Dennis; Department of Aerospace Engineering (2015) Rapid development of nonlinear control theory for application to challenging and complex problems is motivated by the fast technological development and demand for highly accurate control systems. In infinite-horizon nonlinear optimal control the essential difficulty is that no efficient analytical or numerical algorithm is available to derive exact expressions for optimal controls. This work concerns the numerical investigation of faux Riccati equation methods for control of nonlinear and linear time-varyi...
Aerothermodynamic shape optimization of hypersonic blunt bodies Eyi, Sinan (2015-07-03) The aim of this study is to develop a reliable and efficient design tool that can be used in hypersonic flows. The flow analysis is based on the axisymmetric Euler/Navier-Stokes and finite-rate chemical reaction equations. The equations are coupled simultaneously and solved implicitly using Newton's method. The Jacobian matrix is evaluated analytically. A gradient-based numerical optimization is used. The adjoint method is utilized for sensitivity calculations. The objective of the design is to generate a h...
Cogging Torque Disturbance Rejection for a Low-cost Gimbal Motor and a Controller Design with Practical Considerations Ozdogan, Gokhan; Leblebicioğlu, Mehmet Kemal (2019-01-01) In many robotic applications and inertially stabilized electro-optic gimbal systems, precise positioning and speed control are highly important concepts. Due to size and weight limitations, motor is required to be small but torque density is desired to be high. In high torque and cheap PMSM and BLDC motors, cogging torque and friction are usually the challenging disturbance sources. In this study, cogging torque and friction are identified using position sensors which already exist in gimbal systems, so the...
Data-driven manufacturing: An assessment model for data science maturity Gökalp, Mert Onuralp; KAYABAY, KEREM; Koçyiğit, Altan; Eren, Pekin Erhan (2021-07-01) © 2021 The Society of Manufacturing EngineersToday, data science presents immense opportunities by turning raw data into manufacturing intelligence in data-driven manufacturing that aims to improve operational efficiency and product quality together with reducing costs and risks. However, manufacturing firms face difficulties in managing their data science endeavors for reaping these potential benefits. Maturity models are developed to guide organizations by providing an extensive roadmap for improvement in...
