摘要: With the unique ergodicity, irregularity, and special ability to avoid being trapped in
local optima, chaos optimization has been a novel global optimization technique and has
attracted considerable attention for application in various fields, such as nonlinear
programming problems. In this article, a novel neural network nonlinear predic-tive control
(NNPC) strategy based on the new Tent-map chaos optimization algorithm (TCOA) is presented.
The feedforward neural network is used as the multi-step predictive model. In addition, the
TCOA is applied to perform the nonlinear rolling optimization to enhance the convergence
and accuracy in the NNPC. Simulation on a labora-tory-scale liquid-level system is given to
illustrate the effectiveness of the proposed method.
