摘要翻译：
传统的输入输出反馈线性化(IOFL)需要充分的系统动力学知识，并假定输入通道无扰动，系统无不确定性。本文提出了一种基于改进自抗扰控制(IADRC)的无模型主动输入输出反馈线性化(AIOFL)技术，用于设计相对度已知的广义非线性系统的反馈线性化控制律。线性化控制律(LCL)由一类饱和行为的改进非线性扩展状态观测器(INLESO)估计的标度广义扰动和改进非线性状态误差反馈(INLSEF)产生的标称控制律组成。所提出的AIOFL实时地消除了代表所有不需要的动态、外源干扰和系统不确定性的广义扰动，并将系统转化为一个积分器链，直到系统的相对程度，这是非线性系统所需的唯一信息。基于Lyapunov函数进行了稳定性分析，揭示了内环的收敛性和闭环系统的渐近稳定性。将所提出的AIOFL技术应用于柔性关节单连杆机械手(SLFJM)上，对结果进行了验证。仿真结果验证了所提出的基于IADRC的AIOFL工具与传统的基于ADRC的AIOFL和传统IOFL技术相比的有效性。

英文摘要：
  Traditional Input-Output Feedback Linearization (IOFL) requires full knowledge of system dynamics and assumes no disturbance at the input channel and no system's uncertainties. In this paper, a model-free Active Input-Output Feedback Linearization (AIOFL) technique based on an Improved Active Disturbance Rejection Control (IADRC) paradigm is proposed to design feedback linearization control law for a generalized nonlinear system with known relative degree. The Linearization Control Law(LCL) is composed of a scaled generalized disturbance estimated by an Improved Nonlinear Extended State Observer (INLESO) with saturation-like behavior and the nominal control law produced by an Improved Nonlinear State Error Feedback (INLSEF). The proposed AIOFL cancels in real-time fashion the generalized disturbances which represent all the unwanted dynamics, exogenous disturbances, and system uncertainties and transforms the system into a chain of integrators up to the relative degree of the system, the only information required about the nonlinear system. Stability analysis has been conducted based on Lyapunov functions and revealed the convergence of the INLESO and the asymptotic stability of the closed-loop system. Verification of the outcomes has been achieved by applying the proposed AIOFL technique on the Flexible Joint Single Link Manipulator (SLFJM). The simulations results validated the effectiveness of the proposed AIOFL tool based on IADRC as compared to the conventional ADRC based AIOFL and the traditional IOFL techniques.
