9307545 Tao This proposal describes a project to explore a new area of adaptive control and to address open problems of urgent relevance to theory as well as applications: adaptive control of systems consisting of a linear part and a nonsmooth nonlinear input- output characteristic being in either an actuator or a sensor. Typical examples of such nonlinear characteristics are dead-zone, backlash and hysteresis. An adaptive inverse approach is proposed to control such systems to meet desired performance specifications, which exploits an adaptive inverse for an unknown nonlinearity and a linear controller structure nonadaptive/adaptive for a known/unknown linear part. Choices of nonlinear models, design of adaptive inverse control algorithms, stability, convergence and robustness analysis, and applications will be investigated. The results of this research will provide new tools to handle unknown nonsmooth nonlinearities which are common in practical control systems. ***

9307545陶这个建议描述了一个项目，以探索自适应控制的新领域，并解决与理论和应用迫切相关的开放问题：自适应控制的系统，包括线性部分和非光滑非线性输入-输出特性，无论是在执行器或传感器。 这种非线性特性的典型例子是死区、间隙和滞后。 提出了一种自适应逆方法来控制这样的系统，以满足期望的性能指标，它利用一个自适应逆的未知的非线性和线性控制器结构的非自适应/自适应的已知/未知的线性部分。 本课程将探讨非线性模型的选择、自适应逆控制演算法的设计、稳定性、收敛性与鲁棒性分析，以及应用。 本文的研究结果将为处理实际控制系统中常见的未知非光滑非线性提供新的工具。 ***
