本文介绍了一种系统化的方法来合成由输入仿射状态空间(SS)表示描述的非线性(NL)系统的线性变参数(LPV)表示。转换方法导致LPV-SS表示在可观察的标准形式。基于相对度的概念,首先将给定NL表示的SS描述转化为范式。在SISO的情况下,所有的非线性的原始系统被嵌入到一个NL函数,这是因式分解,基于所提出的算法,构建一个LPV表示的原始NL系统。整个过程产生LPV模型,其中调度变量取决于系统的输入和输出及其导数,实现了实际适用的转换的情况下,低阶导数的模型。此外,如果NL模型的状态可以被测量或估计,则提出了一种修改的过程来提供由这些状态调度的LPV模型。包括例子来证明这两种方法。
This article introduces a systematic approach to synthesize linear parameter‐varying (LPV) representations of nonlinear (NL) systems which are described by input affine state‐space (SS) representations. The conversion approach results in LPV‐SS representations in the observable canonical form. Based on the relative degree concept, first the SS description of a given NL representation is transformed to a normal form. In the SISO case, all nonlinearities of the original system are embedded into one NL function, which is factorized, based on a proposed algorithm, to construct an LPV representation of the original NL system. The overall procedure yields an LPV model in which the scheduling variable depends on the inputs and outputs of the system and their derivatives, achieving a practically applicable transformation of the model in case of low order derivatives. In addition, if the states of the NL model can be measured or estimated, then a modified procedure is proposed to provide LPV models scheduled by these states. Examples are included to demonstrate both approaches.
