The objective of this study is to examine the influence of machining parameters on surface finish in face milling. A new approach in modeling surface roughness which uses artificial intelligence tools is described in this paper. This paper focuses on developing empirical models using fuzzy logic and regression analysis. The values of surface roughness predicted by these models are then compared. The...
This paper deals with robust model predictive control (MPC) of an input and state constrained linear system, when the system and controller are separated by a digital communication channel of limited capacity. By extending some existing results within the robust MPC literature, the MPC scheme proposed in this paper employs time-variant ??safety margins?? within the finite horizon optimization problem,...
One of the long standing challenging aspect in mobile robotics is the ability to navigate autonomously, avoiding obstacles especially in crowded and unknown environment. The path followed by a mobile robot and its behavior plays an important role in the quality of localization and mapping as well. To combat this problem, we introduced a real time and robust recursive line extraction algorithm for...
A low complexity method is proposed, suitable for online (i.e. real-time) implementation, for the computation an outer approximation of the reachable set for a stable linear discrete-time system, subject to external disturbances. The set, within which the disturbances are known to lie is bounded, but time-variant. An ??optimal?? outer approximation for the reachable set, the computation of which is...
