基于RBF-ARX模型的改进多变量预测控制及应用
An improved multivariable RBF-ARX model-based nonlinear model predictive control approach and application
摘要
Abstract
For a class of smooth nonlinear multivariable systems whose working-points vary with time, a Gaussian radial basis function (RBF) neural networks-based local linearization autoregressive with exogenous (ARX) model was built to describe the system’s global behavior, and an improved nonlinear model predictive control (NMPC) method with adaptive differential effect based on RBF-ARX model identified offline was presented. Difference from conventional NMPC, the differential of errors between model outputs and designed outputs in whole prediction horizon were considered and their weights were adapted by functions of themselves in each optimization process, thus the controller can improve dynamic performance when the steady-state performance is ensured. A case study on a quadrotor for its real attitude control indicates that the proposed method is effective.关键词
