This article presents and practically validates an identifier-critic-based approximate dynamic programming (ADP) method to online address the optimal tracking control problem for nonlinear continuous-time unknown systems. The imposed assumption on precisely known system dynamics is obviated via a neural network (NN) identifier. A static contro…


The resonant interaction between the energetic particle triggered fishbone mode and the shear Alfven waves is, for the first time, computationally observed and firmly demonstrated based on a tokamak plasma equilibrium, using the self-consistent MHD-kinetic hybrid code MARS-K [Y. Q. Liu et al., Phys. Plasmas 15, 112503 (2008)]. This type of continuu…
