摘要:

本文研究连续时间线性周期(CTLP)系统的无限时间自适应最优控制问题。针对一般类别的CTLP系统,提出了一种基于价值迭代(VI)的离轨自适应动态规划(ADP)算法,从而可以直接从收集的数据中获取近似最优解,无需系统动态的精确知识。在温和条件下,给出了该算法在基于模型和无模型情况下向最优解一致收敛的证明。该基于VI的ADP算法能够在不假设已知初始稳定控制器的情况下找到次优控制器。将该方法应用于受周期性负载作用的三级倒立摆的最优控制,验证了其可行性与有效性。

英文摘要:

This paper studies the infinite-horizon adaptive optimal control of continuous-time linear periodic (CTLP) systems. A novel value iteration (VI) based off-policy ADP algorithm is proposed for a general class of CTLP systems, so that approximate optimal solutions can be obtained directly from the collected data, without the exact knowledge of system dynamics. Under mild conditions, the proofs on uniform convergence of the proposed algorithm to the optimal solutions are given for both the model-based and model-free cases. The VI-based ADP algorithm is able to find suboptimal controllers without assuming the knowledge of an initial stabilizing controller. Application to the optimal control of a triple inverted pendulum subjected to a periodically varying load demonstrates the feasibility and effectiveness of the proposed method.
