在本文中,我们介绍了用于非线性控制系统设计的基于数据驱动反演的控制(D² - IBC)方法。该方法依赖于一种两自由度架构,其中非线性控制器和线性控制器并行运行,并且不需要任何关于被控对象的详细物理知识。具体而言,我们仅使用凸优化工具,利用输入/输出数据来合成控制作用。我们通过一个仿真示例展示了所提方法的有效性,其中还将D² - IBC的性能与直接反馈(DFK)设计方法进行了比较,DFK是一种基于数据的非线性控制器设计的基准方法。
: In this paper, we introduce the Data-Driven Inversion-Based Control (D 2 -IBC) method for nonlinear control system design. The method relies on a two degree-of-freedom architecture, with a nonlinear controller and a linear controller running in parallel, and does not require any detailed physical knowledge of the plant to control. Specifically, we use input/output data to synthesize the control action by employing convex optimization tools only. We show the effectiveness of the proposed approach on a simulation example, where the D 2 -IBC performance is also compared to that of the Direct FeedbacK (DFK) design approach, a benchmark method for nonlinear controller design from data.
