Nonlinear Integral Backstepping Control for Induction Motors
Mehazzem, F.; Nemmour, A. L.; Reama, A.; Benalla, H. (2011-09-10)
A novel structure of nonlinear integral backstepping control has been proposed for induction motors. We can see clearly that the structure of the controller generated by the classical version of backstepping is composed of a proportional action, which was added a derivative action on errors. Such a structure makes the system sensitive to measurement noise. The lack of integration means also the appearance of a constant static error, caused mainly by non-zero mean disturbances. The solution to this problem i...
Shaft transducerless vector control of the interior permanent magnet motor with speed and position estimation using high frequency signal injection and flux observer methods
Göksu, Ömer; Hava, Ahmet Masum; Department of Electrical and Electronics Engineering (2008)
In this thesis, shaft transducerless vector control of Interior Permanent Magnet (IPM) motor with speed and position estimation using saliency based high frequency signal injection and fundamental model based flux observer methods will be investigated. The magnetic saliency characteristic of a 2.2-kW IPM motor will be experimentally extracted by means of high frequency signal injection. High frequency signal injection method will be used to estimate the speed and position at zero and low speed based on the ...
Phase locked dielectric resonator oscillator design and fabrication for receiver systems
Köksal, Remzi; Koç, Seyit Sencer; Department of Electrical and Electronics Engineering (2016)
Oscillators play an important role in transmitters and receivers. In these systems, stable frequency source and low phase noise are critical for system performance. In radio frequencies, phase locked dielectric resonator oscillators are one of the best options in terms of cost, dimension, and performance. These oscillators are widely used in systems such as RADAR, electronic warfare, and communication. In this thesis, design methodology of phase locked dielectric resonator oscillator is given, an oscillator...
Phaseguide assisted liquid lamination for magnetic bead-based assays
Phurimsak, Chayakom; Yıldırım, Ender; Trietsch, Sebastiaan J; Hankemeier, Thomas; Tarn, Mark D; Pamme, Nicole; Vulto, Paul (null; 2013-10-27)
We demonstrate a simple, pump-free platform for performing rapid magnetic bead-based processes via their transfer through sequentially laminated liquid streams, made possible by the use of phaseguide technology. We have applied this strategy to two on-chip assays: (i) a streptavidin-biotin binding assay, and (ii) a sandwich immunoassay for the detection of C-reactive protein (CRP). Here, functionalized magnetic beads were pulled through alternating lanes of reagents and buffer solution, allowing multiple ...
