In the two-coupled distillation column process, keeping temperatures of the trays within a specified range around their steady state values assures the specifications for top and bottom product purity. Normally, the control engineers decouple the process into a group of independent loops and assign one conventional PID controller to each loop. Tuning of(More)
This paper is directed towards developing a new fuzzy-logic based ACO algorithm. The proposed algorithm takes into consideration the uncertainties that can be found in both the heuristic and the pheromone factors. This is achieved by representing the parameters of the problem and the pheromone trails as a pair of value and fuzzy level. The fuzzy level is(More)
This paper presents a new formulation of multi-objective linear optimization using the fuzzy logic-based arithmetic (or visual) representations developed originally by Gabr and Dorrah [1-3]. A modified dual simplex algorithm is proposed as part of the formulation implementation procedure operating in a fully fuzzy environment. Moreover, forward and backward(More)
The two-coupled distillation column process is a physically complicated system in many aspects. Specifically, the nested interrelationship between system inputs and outputs constitutes one of the significant challenges in system control design. Mostly, such a process is to be decoupled into several input/output pairings (loops), so that a single controller(More)
This paper provides a new technique of multi-sensor data fusion to achieve an optimal spatial design and power operation of integrated Renewable Energy Grids (REG). This new approach depends on making a sensor data fusion system depending on the spatial concepts for measuring the important climate parameters, which have a great effect on the performance of(More)
— This paper presents a hierarchical hybrid system modeling and simulation framework using the bond graph. Bond graphs are a domain-independent graphical description of dynamic behavior of physical systems. This means that systems from different domains (electrical, mechanical, hydraulic, thermodynamic, and material) are described in the same way. The basis(More)
This paper provides a method one can model manufacturing processes in hybrid systems framework utilizing simple bond graph to determine the flow of events and differential equation models that describe the system dynamics. Controlling of these systems can be easy to develop. " Modeling and Simulation of thermal Power generation Station for power control "(More)
