Control of trajectile and other systems requires reliable real-time estimates of the system state. The design procedure is the mathematical formulation of the state observer by vector calculus possible by different variants of the observer, the determination of its rectro position, attitude and the dynamic system behavior. State Estimation takes all the telemetry seen so far and uses it to determine...
This paper deals with path planning using cubic Hermite splines in real-time control of wheeled robots. The first part describes the filtering and prediction of the robot position. The discrete form of the extended Kalman filter is introduced on the basis of the robot model. The second part shows a computation of trajectories based on Hermite splines. The details of recomputation of the trajectory...
Adaptive nonlinear output feedback control of GD-FNN(generalized dynamic fuzzy neural network) for underwater robot motion control using forming filter for wave disturbance is presented. This method completely construct nonlinear and uncertain parts of underwater robot by online adaptive learning algorithm without knowing fuzzy neural structure and training phase in advance. Output feedback control...
This paper deals with possibilities of manual control of wheeled robots. The problem is tested on a robot-soccer application. The manual computer-assisted control module creates an interface between game controller and controlled robot. There are several ways of steering implementation. The simplest is a differential steering. The module currently uses semi-automatic steering which provides a capability...
This paper proposes a solution to a door crossing problem in unknown environments for an autonomous wheelchair. The problem is solved by a dynamic path planning algorithm implementation based on successive frontier points determination. An adaptive trajectory tracking control based on the dynamic model is implemented on the vehicle to direct the wheelchair motion along the path in a smooth movement...
In the flat panel display manufacturing, the visual alignment system functions as an important part to get high quality products. In this paper, an observer based control method is suggested to enhance the performance of the visual alignment control system, where the error compensation trajectory is to be changed according to intermittent updates of the observer output which tracks the alignment marks...
This paper presents an indoor navigation scheme for a skid-steering mobile robot using a low-cost gyro sensor and a monocular camera. Based on the kinematic model under nonholonomic constraint, a motion controller is designed, and so as to account for some uncertainties from the wheel-ground friction and slip, the rotational velocity measurement from a gyro is incorporated into the model. This control...
The problem of multi-robot cooperative localization based on relative bearings is researched in this paper. Relative bearings of different robots are fused with motions to improve the localization accuracy of robots. We analyse the situations about relative positions of the robots and their motion trajectories. Some relative positions and motion trajectories of the robots easily lead to not-converged...
