This brief studies the causal consensus problem of singular (descriptor) multi-agent systems with networked communication delays and agents described by general singular systems. For the studied systems, only the information of outputs are available through the network. An observer-based networked predictive control scheme is employed to compensate for the communication delays actively. Further...

-This paper presents a nonlinear generalised predictive control scheme for a squirrel cage motor without speed sensor. Some of the difficulties faced are due to uncertainties in the parameters measurements, high cost to obtain state measurements in addition to the inherently non-linear behaviour. The control scheme presented is composed of a positioning predictive control and an open loop obser...

In this paper, a robust sliding mode prediction model is combined with a sliding mode voltage model observer to achieve a sensorless predictive torque control method. In order to compensate the uncertainties of the stator and rotor resistances and the offset of measured current, sliding mode feedbacks were added to the voltage model observer. To reduce the effect of the errors that are injected...

background and aim: clinical and radiographic diagnoses of dental root fractures have always been difficult and require high accuracy in dental care and treatment. the aim of this study was to compare the diagnostic accuracy of intraoral digital radiography (psp) and cbct in the detection of horizontal root fracture (hrf) and vertical root fracture (vrf). materials and methods: for this experim...

Sixty-six supine portable chest radiographs done on the day of bronchoscopy in 62 critical care unit patients suspected of having pneumonia were examined in a blinded fashion by two radiologists. Quantitative culture results obtained from protected brush catheter (PBC) specimens were compared with chest radiograph scores. For one observer, the sensitivity of the chest radiograph for predicting ...

PURPOSE To evaluate the incremental value of a combination of magnetic resonance cholangiopancreatography (MRCP) and ultrasonography (US), compared to US alone, for diagnosing biliary atresia (BA) in neonates and young infants with cholestasis. MATERIALS AND METHODS The institutional review board approved this retrospective study. The US and MRCP studies were both performed on 64 neonates and...

The reliability and validity of the Attachment Q Sort (AQS; Waters & Deane, 1985) was tested in a series of meta-analyses on 139 studies with 13,835 children. The observer AQS security score showed convergent validity with Strange Situation procedure (SSP) security (r = .31) and excellent predictive validity with sensitivity measures (r = .39). Its association with temperament was weaker (r = ....

We propose a new model predictive control (MPC) approach which is completely based on an observer for the state system. For this, we show semiglobally practically asymptotic stability of the closed–loop for an abstract observer and illustrate our results for a numerical example.
