For a flexible air-breathing hypersonic vehicle model, this paper is concerned with the application of linear control theory to address its complex control problem over wide range of flight conditions. Because of the complexity of the numerical nonlinear model of the vehicle dynamics, a curve-fitted model in closed form is created. Based on the analytical model, a linear parameter-varying (LPV)...

Comparison of static and dynamic control allocation techniques for nonlinear constrained optimal distribution of tire forces in a vehicle control system is presented. The total body forces and moments, obtained from a high level controller, are distributed among tire forces, which are constrained to nonlinear constraint of saturation, through two approaches. For the static control allocation te...

in this paper, the enhancement of vehicle stability and handling is investigated by control of the active geometry suspension system (ags). this system could be changed through control of suspension mounting point’s position in the perpendicular direction to wishbone therefore the dynamic is alternative and characteristics need to change. for this purpose, suitable controller needs to change mo...

Dynamic collaborative driving involves the motion coordination of multiple vehicles using shared information from vehicles instrumented to perceive their surroundings in order to improve road usage and safety. A basic requirement of any vehicle participating in dynamic collaborative driving is longitudinal control. Without this capability, higher-level coordination is not possible. Each vehicle...

In this study, the roll, yaw and depth fuzzy control of an Au- tonomous Underwater Vehicle (AUV) are addressed. Yaw and roll angles are regulated only using their errors and rates, but due to the complexity of depth dynamic channel, additional pitch rate quantity is used to improve the depth loop performance. The discussed AUV has four aps at the rear of the vehicle as actuators. Two rule bases...

ESP is an active safety system for road vehicles to control the dynamic vehicle motion in emergency, the composition and working principle of ESP were introduced in the paper, and the control technology of ESP was studied too. A virtual prototype model of a vehicle model was built in ADAMS/Car, and the yaw fuzzy control co-simulation model of vehicle was established in Matlab/Simulink, to study...

Integrated vehicle dynamics control with the coordination of several vehicle subsystems is considered. The proposed algorithms of subsystem coordination based on restriction weights into the optimal control allocation allow to achieve lower energy consumption without significant impairment of stability of motion and vehicle handling compared with standard control allocation. The proposed contro...

In this paper, the effects of roll center height of McPherson suspension mechanism on dynamic behaviour of a vehicle are first studied, and then the optimum location of roll center of this suspension system is determined for a conceptual Class A vehicle. ADAMS/Car software was used for the analysis of vehicle dynamic behaviour in different positions of suspension roll center. Next, optimization...

Vehicle dynamic safety warning system based on data fusion is researched and designed in this paper. Dynamic information of vehicle, road and environment can be collected in real time. By analyzing and processing these data, active safety warning information is achieved for individual vehicle on different work condition. Security characteristic parameter, road conditions and traffic meteorologi...
