For variable oscillation mechanisms, if output stroke is decreased, output-link force will increase for a same input due to the mechanical advantage. Thus, in order to eliminate input actuator stall phenomena for cases where sudden increase occurs at output load, variable oscillation mechanisms can be employed. In this study, a novel design procedure for seven link two degree-of-freedom variable oscillation mechanisms is proposed. The mechanisms run as a six-link mechanism for a fixed position of a control-link. With this method, a variable oscillation mechanism is designed. It is shown that the design procedure is consistent by performing a kinematic analysis. Also, an approach to switch to second oscillation mode is introduced via underactuation. Finally, it is verified that the theoretical approach proposed is consistent for underactuated switching with Nastran simulation.

A partitioning strategy for improved state estimation performance in ill-conditioned power systems with hybrid measurement set Yildiz, Tuna; Açılan, Etki; Göl, Murat (2021-12-01) Considering the increase in power system size and the number of PMUs, the utilization of a computationally efficient yet accurate static state estimator is crucial. The fast-decoupled WLS estimator (FD-WLS) is the most common method employed in industrial applications, thanks to its computational efficiency and ease of implementation. However, it is known that FD-WLS fails in the presence of an ill-conditioned power system, e.g., a power system with high R/X ratio and large difference between measurement er...
A Complete Analysis for Pump Controlled Single Rod Actuators Çalışkan, Hakan; Balkan, Raif Tuna (null; 2016-03-07) In the current study a variable speed pump controlled hydrostatic circuit where an underlapped shuttle valve is utilized to compensate the unequal flow rate of a single rod actuator is analyzed. Parameters of the shuttle valve are included in the system analysis, rather than treating it as an ideal switching element as handled in literature. A linearized model of the system is obtained. An inverse kinematic model, which calculates the required pump drive speed for a desired actuator speed and given pilot pr...
A Hybrid Method to Estimate Velocity and Acceleration using Low-Resolution Optical Incremental Encoders Baser, Ozgur; Kilic, Ergin; Konukseven, Erhan İlhan; Dölen, Melik (2010-09-10) Accurate velocity and acceleration estimates are required for model-reduced disturbance compensation in motion and force control applications. Such paradigms mostly rely on the position measurements of optical incremental encoders that are known to suffer from the quantization effects introduced by these devices (and their accompanying interfaces). Fixed-time (FT) and fixed-position (FP) methods are used to estimate velocity and acceleration from the quantized position signal. Using Field Programmable Gate ...
A model for predicting vertical component peak ground acceleration (PGA), peak ground velocity (PGV), and 5% damped pseudospectral acceleration (PSA) for Europe and the Middle East Ertuğrul, Zehra; Kale, Ozkan; SANDIKKAYA, MUSTAFA ABDULLAH (2017-07-01) In this study, we present a ground-motion model for the vertical component of peak ground acceleration, peak ground velocity, and 5% damped pseudo acceleration response spectra at periods ranging from 0.01 to 4 s. The vertical model is based on the ground-motion models previously developed for the horizontal component and vertical-to-horizontal ratio of ground motion by Akkar et al. (Bull Earthq Eng 12:359-387, 2014a; 517-547, 2014b) rather than on an independent regression analysis of strong-motion data av...
A novel algorithm for prediction off-line stator leakage inductance and on-line stator resistance of induction motors Sezgin, Volkan; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2009) In vector control of induction motors it is essential to know the parameters of the motor. Known approaches to this problem have some drawbacks. This thesis work is planned to develop solutions to the existing problems. The proposed solutions will be implemented and tested.
