This work examines three methods of adaptive output feedback control for robotic manipulators. Implementing output feedback for control, instead of full-state feedback, allows use of only the position information. The position can be measured quite accurately, while velocity and acceleration measurements tend to get corrupted by noise. As well, having only a position sensor reduces costs in pro...

In magnetic disk drive actuators, requirements to record and read data at higher track densities has made mechanical resonances of the servo actuator, suspension and the head gimbal assembly a critial consideration. The application of piezo electric material in the servo actuator can be used to re ne and accomplish track following in (extremely) high track density magnetic data storage by contr...

A goal of the emerging field of quantum control is to develop methods for quantum technologies to function robustly in the presence of noise. Central issues are the fundamental limitations on the available information about quantum systems and the disturbance they suffer in the process of measurement. In the context of a simple quantum control scenario-the stabilization of nonorthogonal states ...

The paper deals with analysis of dynamic behavior of a feedback flux weakening control of PMSM traction drive for light vehicles. The PMSM flux weakening is very important for traction drives. Two torque control structures were analyzed pure feedback control and feedback control with prediction of the field producing current component. The principles, control structures, simulation and experime...

This paper presents a thorough simulation and experimental evaluation of the concentration control approach for batch and semibatch crystallization. The sensitivity of concentration feedback control is assessed in the case of various disturbances that result in excessive nucleation events. The enhanced robustness of the concentration control is demonstrated against the widely used direct operat...

background: evaluating the effectiveness of reengineering moheb (interventions and sociopsychological supports in disasters) project helps the managers of the welfare organization have feedback on the status of community empowerment against disasters. in this regard, this study aimed to determine the effectiveness of reengineering moheb project to improve the knowledge, attitude, and performanc...

We report on the experimental implementation of an external control for optical feedback solitons using incoherent spatial intensity distributions in a liquid crystal light valve (LCLV) optical single feedback system. The external control provides excellent experimental possibilities for static and dynamic control of the lateral positions of the optical feedback solitons which will be demonstra...

in many active noise control (anc) applications, an online secondary pathmodelling method that uses a white noise as a training signal is required. this paperproposes a new feedback anc system. here we modified both the fxlms and thevss-lms algorithms to raised noise attenuation and modelling accuracy for theoverall system. the proposed algorithm stops injection of the white noise at theoptimum...
