Abstract A path planning for mobile beacon nodes is presented based on the node localization problem of WSN. The beacon nodes define the unknown node position by using ranging method of RSSI. By analyzing defects of a static trajectory, random trajectory, the beacon nodes move to the maximum coverage of unlocated nodes. The simulation result demonstrates that this algorithm obtains good localiz...

This paper focuses on a fixed-time prescribed performance-based Fault-tolerant controller that guarantees the global performance for Trajectory tracking control of air cushion vehicle (ACV). In presence faults, time-varying parameters and environmental disturbances, proposed system in this has good robustness performance. Firstly, an integrated observer disturbances faults is to suppress all un...

This paper describes the modeling of a two-vehicle convoy and the design of a vehicle following controller that tracks the trajectory of the vehicle ahead with prescribed inter-vehicle distance. Kinematic equations of the system are formulated applying standard robotic methodology. We consider autonomous vehicle following without any information obtained from road infrastructure or communicated...

In this study various trajectory tracking and posture stabilization controllers for differentially driven wheeled mobile robots are studied, simulated and their effectiveness compared. Also, various Path Planning and obstacle avoidance techniques are evaluated. In robotics research, trajectory tracking and obstacle avoidance are typically considered as separate problems. The main contribution o...

In this paper, some of the relationships between optimal control and statistics are examined. In a series of earlier papers, we examined the relationship between optimal control and conventional splines and between optimal control and the statistical theory of smoothing splines. In this paper, we present a unified treatment of these two problems and extend the same framework to include the conc...

A method for onboard generation of entry trajectory for variable targets is discussed. Conventional trajectory planning algorithms can only be used for the fixed terminal conditions without considering the variable targets. In case the vehicle needs to alert the entry trajectory due to damage or effectors failure, the entry guidance system must real-time design a feasible entry trajectory accor...

In the last decade, increasing use of NanoSats and CubeSats has made re-entry capsule an emerging research field needing updates in configuration technology. particular, door to advancements terms efficiency re-usability been opened by introduction inflatable and/or deployable aerodynamic brakes on-board electronics for active control. Such technologies allow smaller sizes at launch, controlled...

This article studies the trajectory planning of redundant robots performing tasks within an enclosed workspace. Configuration control of kinematically redundant manipulators using the pseudo-inverse with null-space projection method is a wellknown scheme. One advantage of this method is that the gradient of an objective function can be included in the homogeneous term to optimize the objective ...
