数据驱动的无模型自适应预测控制及其稳定性分析

Data-Driven Model-Free Adaptive Predictive Control and its Stability Analysis

Feilong Zhang

摘要:

针对一类离散单输入单输出非线性系统,提出了一种新的全形式动态线性化(FFDL)数据驱动无模型自适应预测控制(MFAPC)方法。该方法的新颖之处在于不需要预先建立物理模型和李雅普诺夫稳定性理论来进行控制器的设计和理论分析。相反,拟议的MFAPC仅使用一种称为伪梯度(PG)矢量的新动态线性化方法,该方法仅与输入/输出(I/O)测量数据相关。本文的主要贡献是:首先,提出了一种新的具有可调参数的MFAPC;其次,我们证明了所提出的方法的有界输入有界输出稳定性,跟踪误差的单调收敛性和内部稳定性。第三,拟议的MFAPC可被视为当前MFAC的优雅扩展。仿真结果验证了所提出的MFAPC算法的有效性。

英文摘要:

In this paper, a novel full form dynamic linearization (FFDL) data-driven model-free adaptive predictive control (MFAPC) method is proposed for a class of discrete-time single-input single-output nonlinear systems. The novelty of MFAPC is that preliminary physical model and the Lyapunov stability theory are not required for the controller design and theoretical analysis. Instead, the proposed MFAPC only uses a new dynamic linearization method called pseudo-gradient (PG) vector, which is merely related to the input/output (I/O) measurement data. The main contributions of this paper are: First, a novel MFAPC with adjustable parameters is proposed; Second, we have proved the bounded-input bounded-output stability, the monotonic convergence of the tracking error, and the internal stability of the proposed method. Third, the proposed MFAPC can be considered as an elegant extension of the current MFAC. The simulations have been carried out to verify the effectiveness of the proposed MFAPC.
