摘要
提出一种非线性系统预测控制的分层设计方法。首先采用广义线性化状态反馈得到具有指定动态的线性化系统,然后采用基于状态方程的预测控制算法,以获得良好的跟踪性和鲁棒性。最后以仿真例子证实了这种控制方案的有效性。
In predictive control for nonlinear systems, on-line nonlinear prog-
ramming is often reguired which is not suitable for real-time control. In this
paper, a multi-level design scheme of perdictive control for nonlinear systems
is presented. Firstly, a nonlinear state feedback based on extended lineariza-
tion is used to obtain an approximate increamental linearized system. Then
the predictive control is adopted based on the linearized state-space model to
achieve good tracking performance and robustness. The proposed method
reduces the much computation and is thus suitable for real-time control. A
simulation example is also given to demonstrate the good robustness of the
new method.
