The Conventional control approach may not be suitable for non-linear systems and for the systems with considerable parameter variations over a period of time. On the other hand adaptive control techniques proved to be a convenient tool in dealing with the above said systems. The Model Reference Adaptive Systems (MRAS) with performance specifications given in terms of reference model is tried fo...

Android security has become highly desirable since adversaries can easily repackage malicious codes into various benign applications and spread these malicious repackaged applications (MRAs). Most MRA detection mechanisms on Android focus on detecting a specific family of MRAs or requiring the original benign application to compare with the malicious ones. This work proposes a new mechanism, SC...

Noonan syndrome (NS; MIM 163950) is an autosomal dominant disorder and a member of a family of developmental disorders termed "RASopathies," which are caused mainly by gain-of-function mutations in genes encoding RAS/MAPK signaling pathway proteins. Whole exome sequencing (WES) and trio-based genomic triangulation of a 15-year-old female with a clinical diagnosis of NS and concomitant cardiac h...

Senseless induction motor drives are widely used in industry for their reliability and flexibility, particularly in hostile environment. However, the performance of many of previously developed observer based speed sensors in very low speeds of IM drives was not satisfactory. In this paper we present two types of MRAS based speed estimators, one based on the rotor flux and the other based on th...

The advantage of the Model Reference Adaptive Scheme is to establish robustness with respect to bounded disturbances and unmodeled dynamics. In the model reference adaptive system (MRAS), the desired index of performance is given by the reference model. The tracking error represents the deviation of the plant output from the desired trajectory. The adaptive control without having robustness pro...

In this paper, a detail design and description of predictive current control scheme are adopted for three-phase grid-connected two-level inverter its application in wind energy conversion systems. Despite advantages, the controller is very sensitive to parameter variations which could eventually affected on system stability. To solve problem, an estimation technique proposed identify value harm...

Speed feedback is indispensable not only for closed-loop controlled induction motors (IM) but also the state monitoring systems of open-loop IMs. Replacing speed sensors with estimations has many advantages including, e.g., hardware complexity reduction, sensor cabling elimination, and reduction IM drive costs. From various methods estimation proposed in literature, model reference adaptive sys...

To simplify the system structure of permanent magnet synchronous linear motor (PMSLM), optimize kinematic performance control system, and further improve speed tracking accuracy PMSLM, a model-free regulation design PMSLM based on adaptive observer is proposed. Aiming at instability problem caused by parameter uncertainty PI in controller (MFC) ultra-local model proposed, which has strong robus...

In this paper, we show that the association of the PI regulators for the speed and stator currents with a control strategy using the linearization by state feedback for an induction machine without speed sensor, and with an adaptation of the rotor resistance. The rotor speed is estimated by using the model reference adaptive system approach (MRAS). This method consists of using two models: The ...
