This article presents a sliding mode control (SMC) with artificial neural network (ANN) regulator for the doubly fed induction generator (DFIG) using two-level neural pulse width modulation (NPWM) technique. The proposed control scheme of the DFIG-based wind turbine system (WTS) combines the advantages of SMC control and ANN regulator. The reaching conditions, robustness and stability of the sy...

We consider a new approach to improve the performance of reference tracking problems for closed loop stabilized continuous linear systems through the application of a sequence of reference signals initiated by the occurrence of a discrete event. By means of the internal model principle, we show that a change in the reference signal is equivalent to implementing an instantaneous change via the c...

A vision-based automatic tracking system mounted on the ROV Ventana has successfully tracked jellyfish in Monterey Bay, California as part of a joint project between Stanford University and the Monterey Bay Aquarium Research Institute (MBARI). To enhance performance, improved lead information about the target’s motion is desired. Human pilots derive lead information about that motion through th...

One of the most important problems in 3D tracking is the occlusion effect produced by obstacles. To solve this problem, we have developed a tracking system based on optical flow and stereo vision, combinedwith adaptive filters to predict the expected 3D velocities of objects. The critical point of the system is the coupling between tracking and predictive algorithms. We propose the use of a fuz...

Vehicle control systems need to prognosticate future vehicle states in order to improve energy efficiency. This paper compares four approaches that are used to identify the parameters of a longitudinal vehicle dynamics model used for the prediction of vehicle tractive forces. All of the identification approaches build on a standard Kalman filter. Measurement signals are processed using the poly...

in present paper, dynamic behavior and control of a fluidized bed reactor for polyethylene production has been considered. a double active sites model for ziegler-natta catalysts is used for simulation of polymerization reaction. hydrodynamic behavior of the bed is modeled using a two phase model including bubble and emulsion phases in which bubble phase has plug flow pattern with differentiall...
