—An electronic throttle is a dc-motor-driven valve that regulates air inflow into the combustion system of the engine. The throttle control system should ensure fast and accurate reference tracking of the valve plate angle while preventing excessive wear of the throttle components by constraining physical variables to their normal-operation domains. These(More)
An electronic throttle is a low-power dc servo drive which positions the throttle plate. Its application in modern automotive engines leads to improvements in vehicle drivability, fuel economy, and emissions. Transmission friction and the return spring limp-home nonlinearity significantly affect the electronic throttle performance. The influence of these(More)
— PieceWise Affine (PWA) model comprises several affine dynamics defined over polyhedral regions in the regressor (state+input) space. Identification of a PWA model is very often a starting point for the controller synthesis of hybrid systems. In this paper we extend the clustering-based procedure for identification of a PieceWise AutoRe-gressive eXogenous(More)
One of the basic issues in navigation of autonomous mobile robots is the obstacle avoidance task that is commonly achieved using reactive control paradigm where a local mapping from perceived states to actions is acquired. A control strategy with learning capabilities in an unknown environment can be obtained using reinforcement learning where the learning(More)
—Before applying current-signature-analysis-based monitoring methods, it is necessary to thoroughly analyze the existence of the various harmonics on healthy machines. As such an analysis is only done in very few papers, the objective of this paper is to make a clear and rigorous characterization and classification of the harmonics present in a healthy cage(More)
The use of wind power for generating electricity has experienced an uninterrupted and accelerating growth over last few decades and this growth is likely to continue. In order to enable even greater role of wind energy in power production it is necessary to increase the size and unit power of wind turbines. As wind turbines grow in size they are subjected(More)
In this paper a neural network based sliding mode controller for electronic throttle is proposed. Electronic throttle is considered as an uncertain linear system. The uncertainties , which consist of an unknown friction and spring torque are estimated by the neural network whose parameters are adapted in an on-line fashion. Control and adaptive laws(More)
