Partricular features of overpassing local optima and providing near-optimal soultion in practical time has led researchers to apply metaheuristics in several engineering problems. Optimal design of diagrids as one of the most efficient structural systems in tall buildings has been concerned here. Jaya algorithm as a recent paramter-less optimization method is employed to solve the problem using...

This paper presents a decentralized control problem for stabilizing the nonlinear large-scale descriptor (LSD) systems that use proportional-plus-derivative state (PD) feedback scheme. The have great focus on research because they can contain more physical characteristics than standard state-space systems. At first, each subsystem in LSD system be represented by Takagi-Sugeno (T-S) with interco...

Design and Performance of Passive Control System for Gas-Liquid Cylindrical Cyclone Separators by Ram Mohan, Shoubo Wang, & Ovadia Shoham, The University of Tulsa and Gene Kouba, Chevron Petroleum Technology Company Abstract: The performance of Gas Liquid Cylindrical Cyclone (GLCC) separators can be improved by reducing or eliminating liquid carry-over into the gas stream or gas carry-under thr...

There has been an increasing interest in the study of underactuated robotics toward significant improvement of behavioral performances in robotic systems. The previous studies on underactuated robots have demonstrated energy efficient, maneuverable, and robust motion control by properly exploiting passive dynamics. Despite these fascinating characteristics in underactuated systems, however, the...

in this paper the optimal design of a dissipator made of aluminium and steel and principallysubjected to shear forces and the preliminary results of the characterization tests are described.the device has been designed on the basis of an optimization procedure with the objective tomaximize the energy dissipated in the device. the response of a 3d frame equipped with thedevice and subjected to 7...

This paper illustrates the mathematical modeling of passive suspension system and the control strategies for semi active suspension system. The Simulink software developed by Matlab is used to evaluate the control characteristics [1], for the same a 2 DOF quarter car model is used. The comparison and evaluation of control result are made using software-in-the-loop simulation (SILS) method. From...
