摘要

The problem of almost disturbance decoupling (ADD) for a class of inherently nonlinear systems with nonlinear parameterization is considered. The controlled systems are beyond triangular form and possess uncontrollable linearization. The performance of ADD is characterized in terms of L-2 - L-2p. By using the tool of adding a power integrator combined with the parameter separation technique, under a set of growth conditions a smooth one-dimensional adaptive controller is explicitly constructed to attenuate the influence of the disturbance on the output with an arbitrary degree of accuracy.
