论文摘要
当前无模型自适应控制（MFAC）方法尚未在线性系统中进行分析，并且对于实践工程师来说并不直接准确地理解。该对应关系为基于修改的等效动态线性化模型（EDLM）的MFAC家族提供，该模型促进了更直接，客观地显示方法的工作原理。与当前的工作相比，i）MFAC的研究重点是线性模型，这很容易理解其工作行为； ii）全格式EDLM分别以未测量的随机和测量的干扰扩展。然后相应地修改控制器； iii）当当前收缩映射技术的稳定性分析无法证明控制输入变化的迹象时，我们通过分析闭环电线杆的功能来证明这一点。几个模拟示例用于显示这种方法的原理。
Current model-free adaptive control (MFAC) method has no been analysed in linear system and is not straightforward for the practical engineers to understand accurately. This correspondence presents a family of MFAC based on a modified equivalent-dynamic-linearization model (EDLM), which facilitates to show the working principle of method more directly and objectively. Compared to the current work, i) the researches on MFAC focus on linear model, which is easy to understand its working behaviour; ii) the full-form EDLM is extended with unmeasured stochastic and measured disturbance, respectively. Then the controllers is modified correspondingly; iii) the stability analysis of system cannot be proved by current contraction mapping technique when the sign of leading coefficient of control input changes, therefore we prove it by analysing the function of the closed-loop poles. Several simulated examples are used to show the principles of this kind of method.
