The autonomous vehicle is a mobile robot integrating multi-sensor navigation and positioning, intelligent decision making control technology. This paper presents the system architecture of vehicle, called “Intelligent Pioneer”, path tracking stability motion to effectively navigate in unknown environments discussed. In this approach, two degree-of-freedom dynamic model developed formulate path-tracking problem state space format. For controlling instantaneous error, traditional controllers...
Next point-of-interest (POI) recommendation aims to predict a user's next destination based on sequential check-in history and set of POI candidates. Graph neural networks (GNNs) have demonstrated remarkable capability in this endeavor by exploiting the extensive global collaborative signals present among POIs. However, most existing graph-based approaches construct graph structures pre-defined heuristics, failing consider inherent hierarchical features such as geographical locations...
Simultaneous localization and mapping is a mobile robot positioning themselves creating the map of environment at same time, which core problem vehicle achieve authentic intelligent. EKF-SLAM widely used SLAM algorithm based on extended Kaiman Alter. The proposed in this paper differential model motion, consider trajectory as many small straight Une segments. effectively reduce error compared with dead reckoning has more simplified generic kinematics model. Meanwhile, it lower requirements...
In this paper, a hierarchical driving force distribution and control strategy for six-wheel drive (6WD) skid-steering electric unmanned ground vehicle (EUGV) with independent motors is presented to improve the maneuverability stability. The proposed based on nine-degrees-of-freedom (DOFs) dynamics model of 6WD EUGV system model, wheel tire model. strategy, upper layer controller calculates resultant yaw moment motion states track desired ones by using integral sliding mode (ISMC)...
The paper presents the architecture of an unmanned vehicle called `Intelligent Pioneer' developed by authors. has ability navigating in urban environments autonomously without GPS or any other satellite navigation system. is able to select its own routes perceive traffic signs and interact with vehicles pedestrians under rules. Various driving skills including lane keeping, U-turns, parking, obstacle avoidance, merging into moving have been for vehicle. attended Future Challenge Intelligent...
For the problem that path following performance is degraded due to model uncertainty of unmanned ground vehicle(UGV) during lateral maneuvering,a double loop control structure designed,in which external and yaw stability inner respectively.A robust based on μ synthesis proposed.Simulation results show UGV this method has better than PID(proportional-integral-derivative) H∞ controller when parameters are changed.In comparison experiments,the root mean square error 1/3 less PID.The result...
Negative damping oscillation and forced power are two typical kinds of low frequency (LFO). The control devices the generator including governor exciter main source oscillation, which have essential differences to cause LFO. Thus locating identifying LFO correctly is great importance adoption reasonable suppression methods improvement system stability. This paper presents a method locate identify sources based on contribution phase shift characteristics disturbance source. Firstly, study...
In response to the complex terrain structure in field and lack of passability traditional wheeled tracked robots, this paper proposes designs a six-tracked robot that can adapt environments by adjusting track rotation angle through six independently driven foot-track mechanisms achieve multiple posture changes. The center mass plays key role process obstacle surmounting, establishing centroid kinematics model based on coordinate formula, influence cantilever motion is analyzed, change during...
We study the properties of exciton excitations in Hubbard model with alternating potential and dimerized hopping terms at half-filling. With increasing Coulomb repulsion, we find that a spin triplet band develops below gap. At certain critical interaction, excitation gap this vanishes new phase ground state emerges. The value interaction is determined perturbatively.
For single material element, the same element is comprised of Relatively Non-Disturbed(RND) state and Complete Disturbed (RCD)state considered.The ratio two kinds changes with loading level.The affection interaction between RND RCD to apparent behavior 0 F considered in analysis equilibrium equations.The key point method that response can be defined by element.5]
