一类Lorenz型混沌系统的直接数据驱动控制
Direct data-driven control for Lorenz-type chaotic systems
摘要
Abstract
The direct data-driven control problem of an unknown class of Lorenz-type chaotic systems was investigated.The systems were transformed into linearly dependent form to construct the non-parameterized model.The state feedback controller was designed for the reconstructed system.The input and output data of the system were sampled offline,and the collected data were directly used to design and give the expression of the state feedback controller.The stabilization problem of the system under state feedback control was verified,and the stability of the closed-loop system was proved.Through numerical example simulation verification,the results show that the proposed direct data-driven control strategy is effective.关键词
