Sequential multiobjective optimization method based on radial basis function model is presented in this work to deal with the multiobjective design and optimization problems of engineering electromagnetic devices. Firstly, the initial sample set can be generated by using the sequential optimization method (SOM). SOM can greatly reduce the sample size by integrating the advantages of optimization algorithms...
Organic Rankine Cycle (ORC) is suitable for recovering energy from low-grade heat sources. A moving boundary model is introduced to describe the transient phenomena of evaporator, which is an important component of ORC. Based on the partial-differential equations expressing the conservation principles of mass and energy, coupled with flue gas and tube wall energy equations, a set of ordinary-differential...
The objectives of this study were to improve our previous portable impedance biosensor instrument with more rapid, reliable and quantitative features for detection of avian influenza (AI) virus and to evaluate its performance using H5N1 and H5N2 virus. A high-intensity and high-gradient magnetic field based separator was designed and fabricated for rapid separation of AI virus. KPL measuring solution...
Three degrees of freedom air-bearing Spacecraft simulator have been used for spacecraft attitude determination and control hard verification and software development. In this paper, some details about the simulator are described. The equation of motion of the platform and proof masses on which are deduced according to the assumption that the total angular momentum is zero. An important feature of...
Model selection strategy is investigated for sequential optimization method (SOM) to deal with the optimization design problems of electromagnetic devices. Four kinds of approximate models, response surface model, radial basis function model, Kriging model and artificial neural network model are considered respectively. From the analysis of two mathematic test functions and an IEEE TEAM benchmark...
This paper presents a modeling of lateral electrostatic comb drive actuator and develops a 2D finite element model using reduced order modeling (ROM) principles to analyze the coupled field. This technique reduces the comb drive to a group of equivalent lumped parameters finite elements which capture the device behavior. Finally, Simulation results are validated using an analytical approach, both...
This paper presents a fast global optimal method for the optimization design of electromagnetic device, which based on the approximation models and the global optimization algorithms. Two approximate models, radial basis functions model and compactly supported radial basis functions model, are fully discussed in this paper. In order to illustrate the efficiency and robustness of the proposed method,...
