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.
