This work represents a mathematical analysis and simulation of dc-motor electric drive control system with variable moment of inertia. A separately-excited dc motor is used in this control system. A mathematical model for this motor has been simulated and tested in Matlab/Simulink. A closed-loop control system for this dc electric drive system is proposed. The proposed control system is based o...

Modern trains rely on balises (communication beacons) located on the track to provide location information as they traverse a rail network. Balises, such as those conforming to the Eurobalise standard, were not designed with security in mind and are thus vulnerable to cyber attacks targeting data availability, integrity, or authenticity. In this work, we discuss data integrity threats to balise...

BACKGROUND to develop a physical training programme to improve balance in dependent, demented, people with a history of falling, and so decrease falls and increase autonomy. METHODS the study was undertaken on 20 demented elderly people with a history of falling with an average age of 81.4+/-4.7 years and an average mini mental state score of 16.3+/-6.5. They had all passed 'get up and go', '...

Design of reliable and robust controller for electric vehicle in urban and sub urban areas is very much challenging task due to time varying load torque requirement at the wheel of the vehicle. In this paper indirect field oriented vector control of induction motor, PI speed control with anti-windup scheme and hysteresis current control scheme have been proposed for three phase induction motor ...

Induction Motors have been used as the workhorse in the industry for a long time due to its easy build, high robustness, and generally satisfactory efficiency. However, they are significantly more difficult to control than DC motors. One of the problems which might cause unsuccessful attempts for designing a proper controller would be the time varying nature of parameters and variables which mi...

Wind energy is increasing penetration levels on utility grids as more wind turbines are being installed. As the penetration of wind energy increases, there is motivation for wind turbines to actively control their power output to meet power set points provided by grid operators and assist with frequency regulation. This paper focuses on the development of a novel wind turbine control system tha...

In the paper, we describe a series of stages in the development of a new virtual locomotion device designed to enhance remote, interpersonal communications. The latest system, called GSS (Ground Surface Simulator) , inherits the features of two previous locomotion interfaces, i.e. ATLAS (ATR Locomotion Interface for Active Self Motion) and ALF (ALive Floor). GSS also incorporates two different ...

This work gives a short overview of the role that model predictive control has in the development of the advanced wind turbine control algorithms. The advantages of model predictive control compared to conventional controllers involved in wind turbine control are outlined. Wind turbine model predictive speed controller based on identified piecewise affine discrete-time statespace model is desig...
