A fuzzy basis function vector-based multivariable adaptive controller for nonlinear systems

Abstract: In this paper, a new fuzzy basis function vector (FBFV) approach for the adaptive control of multivariable nonlinear systems is presented. With this method, the nonlinear plant is first linearized. The linearized bias and uncertainties as well as disturbances are assumed to be included in the model structure and their upper bound will be adaptively learned by the FBFV method. The output of the FBFV is used as the parameters of the robust controller in the sense that both the robustness and the asymptotic error convergence can be obtained for the multivariable nonlinear system. The effectiveness of the proposed analysis and design method is illustrated with a simulated example.

Identifying risk factors of IT outsourcing using interdependent information

Abstract: Risk factor identification of IT outsourcing is significant to capture the source of IT outsourcing risk. Risk factors of IT outsourcing are often interdependent, and consequently the interrelationships among factors affect risk factor identification, whereas this fact is neglected in the existing studies. The purpose of this paper is to investigate a method for identifying risk factors of IT outsourcing, in which the interrelationships among risk factors are considered. Firstly, the risk factors of IT outsourcing are figured out through literature review and expert interview. Then, the interrelationships among risk factors and relative analysis are given. Furthermore, based on the 2-tuple fuzzy linguistic representation model and the classical Decision Making Trial and Evaluation Laboratory (DEMATEL) method, an extended DEMATEL method is developed to identify the importance together with the classification of risk factors. Finally, the potential of the proposed method is shown through an illustrative example of a Chinese resource company.
