This paper deals with the design of a discrete time nonlinear observer for an anaerobic digestion process. The designed observer is devoted to a general class of systems, precisely linear systems, LPV systems with known and bounded parameters, and nonlinear Lipschitz systems. In order to ensure stability of the estimation error, a new LMI condition is proposed. In this LMI, additional decision variables...
This paper proposes a modified iterated greedy algorithm for solving an NP-hard knapsack problem known as the knapsack problem with setup. In contrast to the classical 0–1 knapsack problem, items belong to different classes, and choosing at least one item from a specific class causes a class setup capacity to be consumed and a reduction of the total profit in terms of a penalty that has to be paid...
In this work, a hybrid system has been simulated and optimized, this system is composed with three generators, two on renewable energy (solar and wind power) and a diesel generator. This central distributes energy to a small village in southwest of Algeria named “Timiaouine”, this central has been sized using mathematic parameter and repartition of consumption for 24 hours in both seasons; winter...
