A Speed-gradient-based Method to Passify
نویسنده
چکیده
This paper proposes a method in order to render passive nonlinear affine-incontrol discrete-time systems. The methodology is based on the discrete-time version of the speed-gradient (SG) algorithm. For the application of the SG algorithm, quasiV -passive and feedback quasi-V -passive systems are introduced. Two kinds of feedback laws rendering the system locally quasi-V -passive are obtained: a dynamic one and a static one. The passification methodology is applied to two examples. Some frequency-domain properties of the feedback transformed system are highlighted for the linear example Copyright ©2005 IFAC

A conjugate gradient based method for Decision Neural Network training
Decision Neural Network is a new approach for solving multi-objective decision-making problems based on artificial neural networks. Using inaccurate evaluation data, network training has improved and the number of educational data sets has decreased. The available training method is based on the gradient decent method (BP). One of its limitations is related to its convergence speed. Therefore,...
