The face inversion effect, evidence that humans possess a specialized system for face processing, and the (3/4) view advantage, evidence that a canonical viewpoint exists from which faces may be optimally recognized, are two commonly cited findings in the face processing literature. In this paper, the interaction of these effects is examined in a sequential matching paradigm in which unfamiliar...

In this paper, stabilizing control of tracked unmanned ground vehicle in 3-D space was presented. Firstly, models of major modules of tracked UGV were established. Next, to reveal the mechanism of disturbances applied on the UGV, two kinds of representative disturbances (slope and general disturbances in yaw motion) were discussed in depth. Consequently, an attempting PID method was employed to...

non-linear characteristic of tire forces is the main cause of vehicle lateral dynamics instability, while direct yaw moment control is an effective method to recover the vehicle stability. in this paper, an optimal linear quadratic regulator (lqr) controller for roll-yaw dynamics to articulated heavy vehicles is developed. for this purpose, the equations of motion obtained by the matlab softwar...

Many vehicle control systems were designed and implemented in the last years to enhance performances and stability acting on front and/or rear steering actuators [1,2,3] and/or individual wheel braking [8]; the development of electroactuated differentials allows to transfer torque between wheels from the faster to the slower one in semiactive differentials [11,12,13,14] and in both directions i...

Many active safety systems in automotive vehicles, for instance yaw stability systems such as ESC/ESP, depend on information about vehicle velocity, in particular lateral velocity or side-slip angle, to be able to function properly. However, the vehicle velocity is rarely measured directly due to issues of cost and reliability, and must therefore in general be inferred from other measurements, ...

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...

Various methods are presented to control the attitude of satellite due to lack of information of yaw axis attitude so far. In this paper, a new method is used which is more general and is applicable to all types of satellites, with at least one controller. This method is not limited to YAW axis and can control the two other axes as well. One feature of this approach is the ability to be modi...

With the characteristics of input nonlinearity, time-varying parameters and the couplings between main and tail rotor, it is difficult for the yaw dynamics of Rotorcraft to realize good tracking performance while maintaining stability and robustness simultaneously. In this paper, a new kind of robust controller design strategy based on active modeling technique is proposed to attenuate the unce...

We investigated effects of roll (rotation around line of sight) and pitch (rotation around the horizontal axis) components of retinal flow on heading judgement from visual motion information. It was found that performance level of human observers for yaw (rotation around the vertical axis) plus pitch is little different from that for only yaw although there is bias in perceived heading toward t...
