Short primary linear drives on passive track are advantageous in material handling applications, where high precision, long track and a closed path are required. This paper presents a linear induction motor (LIM) drive with short primary (moving windings), in which a contactless energy transmission provides the basic power and an ultracapacitor (UC) storage system provides the peak power. The system uses a bidirectional DC-DC converter between the ultracapacitor bank and the DC link, to make sure that the ultracapacitor can store the braking energy and supply the peak power demanded by the active vehicle. A control strategy has been developed for controlling the ultracapacitor to deliver the peak of power, to charge, to protect against overvoltage and to recover the energy generated when the vehicle is braking. Experimental results of the short primary linear induction motor and the bidirectional DC-DC converter are presented, and the control strategy is discussed.

Design, Development and Implementation of Sensorless Digital Control of an Electric Motorization Dida, Abdelkader Hadj; Bourahla, M.; Ertan, Hulusi Bülent; Benghanem, M. (2014-09-24) The most industrial applications use the variation of the torque, speed and/or position in process, for which extremely severe specifications are needed. In the field of the drive of the electric machines, the elimination of the mechanical speed sensor can present an economic interest and improve safety of operation. One thus tries to make fulfill the speed measurement by implementing in a Digital signal processor (DSP) an algorithm of speed estimation using the current and voltage acquisition. Those method...
Optimum Profile Modifications for the Minimization of Dynamic Transmission Error ÖZTÜRK, VEYSEL YALIN; Ciğeroğlu, Ender; Özgüven, Hasan Nevzat (2014-08-28) An optimization study is performed target being the reduction of dynamic transmission error (DTE) for a selected operational range, where the operating torque and speed ranges are defined. For this purpose, two different models, i.e. a single degree of freedom (SDOF) lumped gear dynamics model and a multi-degree of freedom (MDOF) lumped model of a gear pair which is combined with shaft and bearing dynamics are employed. The differences between the optimization results obtained through loaded static transmis...
Parallel Hybrid Genetic Algorithm and GIS-Based Optimization for Municipal Solid Waste Collection Routing Düzgün, H. Şebnem; Uşkay, S. Onur; Aksoy, Ayşegül (American Society of Civil Engineers (ASCE), 2016-01-01) A vast majority of studies on municipal solid waste (MSW) collection routing do not consider the constraints pertinent to actual road networks such as unidirectional roads and terrain characteristics. As a result, good practices such as the avoidance of U-turns cannot be used. This study introduces geographic information system (GIS)-integrated software (RouteSW) for the optimization of MSW collection routes by considering path constraints. The software uses a parallelized hybrid genetic algorithm (PHGA) to...
Sliding mode control for non-linear systems with adaptive sliding surfaces Durmaz, Burak; Özgören, Mustafa Kemal; SALAMCİ, METİN UYMAZ (2012-02-01) This study covers the sliding mode control design with adaptive sliding surfaces for a class of affine non-linear systems, which can be described by (x) over dot = A(x)x + B(x)u + f(x) + d(x, t). The main streamline of the study is the sliding surface design for such systems. The sliding surfaces are designed to be moving with varying slopes and offsets. The varying sliding surface parameters are determined by solving the state-dependent Riccati equations online during the control process. Thus, the sliding...
Experimental investigation of shaft transducerless speed and position control of ac induction and interior permanent magnet motors Goksu, Omer; Hava, Ahmet Masum (2010-01-01) In order to drive AC motors with high efficiency and high motion performance, and to provide accurate speed/position control, motor shaft speed and/or position feedback is required. For this purpose, usually transducers (encoder, tachogenerator, resolver, etc.) are installed on the shaft. However, transducers are not preferred in most of the applications since they increase the cost and decrease the reliability of the drive due to their failure prone structure and connections. In such applications, the spee...
