This paper is aimed at finding the optimal locations of collocated actuator and sensor pairs for active vibration control of cable-network antenna reflectors. The front cable net of the antenna is considered as the control plant. The optimal criterion for placement of actuator and sensor pairs is to choose locations that simultaneously maximize the H2 norms of each dominant mode, and simultaneously...
Mill is acknowledged as main crushing equipment in the ore dressing and smelting process. In addition, the mill load is considered as one of the critical parameters during the operation of crushing equipments. In light of complexity, nonlinearity and uncertainty of the mill load control, an improved neural network control strategy based on chaotic particle swarm optimization was proposed. To realize...
In this paper, optimal control problems considering agile turn of missile as maximizing terminal velocity at boost phase are dealt. The missile in the phase experiences dramatic variation in velocity, mass and angle of attack within finite duration. This research at first, classifies the missile models into two different cases; longitudinal motion and lateral motion, but all of the models neglect...
This paper provides a distributed coordination law for energy distribution in smart grid networks. A distributed optimization scheme is designed to meet supply-demand balance in overall network. To impose lower and upper boundaries in energy flow, we use high-order polynomials in the definition of cost functions. By using high-order polynomials, we could develop a distributed optimization scheme taking...
In many cases, solving optimisation problems, in particular a dynamic optimisation problem, is time-consuming. This is due to the long time of calculation of the objective function value. For example, during optimisation of the articulated vehicle it is necessary to integrate dynamic equations of motion in the whole time interval. The paper presents an application of own algorithm (EVCA) for reduction...
This paper shows a PI with phase-lead controller design using convex-concave optimization. The phase-lead term is added to reduce a high frequency measurement noise effect. By fixing all parameters of the phase-lead part, the optimization program searches the remain parameters subject to robustness constraints. The optimization constraints are functions in a frequency domain. The design problem can...
