Localization with respect to a reference model is a key feature for mobile robots. Urban environment offers numerous landmarks that can be used for the localization process. this paper deals withthe use of an environment model stored in a Geographic Information System, to drive a vision system i.e. highlights what to look for ? and where to look for ? this task is achieved by propagating uncertainties along the image acquisition system to highlight some Region Of Interest in the image.

In this paper a designing method is presented to find stabilizing saturated linear controllers for linear discrete time singular systems withcontrol constraints. the idea is the following: the system is first stabilized by a low-gain linear state feedback control. A general Lyapunov function is found, on the basis of which another linear state feedback control is computed. the two controls are added and saturated.

In this paper, an adaptive fuzzy control strategy is developed for robotic manipulators to guarantee both global stability and performance. A controller output error method (COEM) is introduced and applied to the design of adaptive fuzzy control system. the proposed control strategy employs a gradient descent algorithm to minimize a cost function which is based on the error of the controller output and is minimized by tuning some or all of the parameters of fuzzy controller. the simulation results show that the proposed control is effective and yields superior tracking performance.

Transmitter power control has been proven to be an efficient method to solve co-channel interference in CDMA system, and to increase the capacity of systems. A novel distributed power control algorithm based on estimates of channel gains is presented in this paper. the proposed algorithm is robust and does not require the exact knowledge of channel gains. In the proposed scheme, power control problem is converted into the zero point problem of a certain function. It is proved that the algorithm converges to the average optimal solution by stochastic approximation approach.
