研究了一类非线性系统的输出反馈全局输出调节问题。由未知线性外系统产生的干扰被完全补偿。假设外系统的阶是已知的，并且特征值是不同的。在控制设计中不需要其他假设。这意味着，所提出的控制设计是能够完全补偿的干扰，而不知道他们的振幅，频率和相位，只要在干扰中的不同频率分量的数量是已知的。一个新的制定的状态估计，以确保监管是一个全球性的状态变量。一种自适应控制技术是用来处理不确定性在以前介绍的制定外系统。在所提出的控制设计中，一些控制系数是自适应的，使该规定是全球性的未知频率的干扰。
Deals with global output regulation of a class of nonlinear systems using output feedback. The disturbances generated from a unknown linear exosystem are completely compensated. The order of the exosystem is assumed known and the eigenvalues; are distinct. No other assumptions are needed in the control design. This means that the proposed control design is able to completely compensate the disturbances without knowing their amplitudes, frequencies and phases, as long as the number of different frequency components in the disturbances is known. A new formulation of state estimation is introduced to ensure the regulation is a global one with respect to state variables. An adaptive control technique is used to deal with uncertainty in a previously introduced formulation of exosystems. In the proposed control design, a number of control coefficients are made adaptive so that the regulation is global with respect to unknown frequencies in the disturbances.
