Since the emergence of PID controllers, control system engineers are in pursuit of more and more sophisticated versions of these controllers to achieve better performance, particularly in situations where providing a control action to even a minimal degree of satisfaction is a problem. This work is an attempt to contribute in this field. Variations in the values of weight, the friction coeffici...

As part of the Challenge X competition, the University of Tennessee has chosen a hybrid electric powertrain architecture for conversion of a 2005 Chevrolet Equinox SUV to a more fuel efficient and environmentally responsible vehicle. A brief overview of the powertrain configuration is presented, as well as the corresponding supervisory control system architecture. The methodology for developing...

After a presentation of the real time system analysis and design, we present the Structured Analysis for Real Time Systems, or SA-RT. This graphical design notation is focusing on analyzing the functional behaviour and information flow through a system. In fact, the modeling of the real time systems helps us to understand its working, without eliminating its complexity. Then, we present the gra...

A control scheme for emergency braking of vehicles is designed. The tire/road friction is described by a LuGre dynamic friction model. The control system output is the pressure in the master cylinder of the brake system. The controller utilizes estimated states for a feedback control law that achieves a near maximum deceleration. The state observer is designed using linear matrix inequality (LM...

BACKGROUND The purpose of this research was to examine whether waterpipe smokers experience increased risk of motor vehicle crashes. METHODS In a telephone survey, a random sample of Iranian drivers were asked to report their age, gender, vehicle age, whether their vehicles were equipped with anti-lock braking system (ABS), average daily drive time (DDT), whether they smoked cigarette or wate...

In order to further improve the braking performance of nonlinear antilock system (ABS), an improved global sliding mode control scheme is presented. First, a surface designed. The method can eliminate reaching phase compared with conventional linear surface, and guarantee robustness during whole process. Then, novel law proposed satisfy condition, theoretical proof given. Simulation results dem...
