摘要:

提出了一种适用于线性系的学习模型预测控制器。所提出的控制器是LMPC [1]的扩展,其目的是减少计算负担。该控制方案是无参考的,并且能够通过从以前的迭代中学习来提高其性能。使用凸安全集和终端费用函数,以保证递归的可行性和不增加的性能在每次迭代。本文介绍了控制设计方法,并展示了如何递归地构造凸终端集和终端成本从以前的迭代状态和输入轨迹。仿真结果表明了所提出的控制逻辑的有效性。

英文摘要:

A Learning Model Predictive Controller (LMPC) for linear system in presented. The proposed controller is an extension of the LMPC [1] and it aims to decrease the computational burden. The control scheme is reference-free and is able to improve its performance by learning from previous iterations. A convex safe set and a terminal cost function are used in order to guarantee recursive feasibility and non-increasing performance at each iteration. The paper presents the control design approach, and shows how to recursively construct the convex terminal set and the terminal cost from state and input trajectories of previous iterations. Simulation results show the effectiveness of the proposed control logic.
