The main concern of this paper focuses on the accurate estimation of the vehicle states, including the longitudinal, lateral, and vertical velocities (hence, sideslip angle), as well as the roll and pitch angles. With the input data from the 6D IMU which measures both acceleration and angular velocities of the three axes, the novel merging schemes based on the internally defined concepts of tra...

Contemporary morphing designs are focused towards enabling a vehicle to transition from one distinct flight regime to another. Such a change often requires highly complex morphing that is designed to address both aerodynamic performance and handling criteria. The University of Florida has developed a morphing demonstrator to investigate the effect of a biologically-inspired gull-wing morphing o...

Hypersonic airbreathing vehicles are characterized by highly-integrated airframe and propulsion system. Computational Fluid Dynamics (CFD) tools have been used extensively in the design and analysis phrase of hypersonic vehicles. In this paper, an engineering method and a finite volume method based on the center of grid are developed for preliminary research of interested integrative hypersonic...

The unified dynamics modeling of automobile chassis is the foundation integrated control. Previous researches mainly focused on one or two subsystems, which could not fully reflect characteristics chassis. In this paper, a mathematical model involving 18 degrees freedom (DOF) two-axle vehicle established to evaluate ride comfort and handling stability vehicle, based coupling relationship longit...

Dynamic robustness and stability control is a requirement for self-driving of autonomous vehicle. Longitudinal control technique of autonomous vehicle is basic theory and one key complex technique which must have the reliability and precision of vehicle controller. The longitudinal control technique is one of the foundations of the safety and stability of autonomous vehicle control. In our pape...

This paper describes the fundamental principles of launch vehicle flight control analysis and design. In particular, the classical concept of “drift-minimum” and “load-minimum” control principles is re-examined and its performance and stability robustness with respect to modeling uncertainties and a gimbal angle constraint is discussed. It is shown that an additional feedback of angle-of-attack...

Abstract: In this paper, an FD scheme for detecting sensor faults in Lateral dynamics system is presented. The main contribution is to present an analytical solution to design residual generator using parity space approach in order to handle the time varying parameter in the system. The designed residual generator is realized in an observer structure which provides numerical stability by on-lin...

To improve the stability and accuracy of quintic polynomial trajectory tracking, an MPC (model predictive control) fuzzy PID (proportional-integral-difference)- based control method are proposed. A lateral tracking controller is designed by using with rule-based horizon parameters. The controls steering angle to reduce errors. longitudinal a PID. motor torque brake pressure referring throttle/b...

introduction: functional ankle instability has described as a “feeling of giving way”. balance control deficit is one of the sensorimotor impairments observed in people with functional ankle instability that has been described to damage to the afferent receptors within the ligaments and joint capsule that affected during sprain. foot orthosis can improve balance control via enhanced sensory aff...
