【Abstract】 The problem of adaptive disturbance attenuation is addressed for a class of nonlinearly parameterized delayed systems with unknown virtual control coefficients.Using parameter separation and backstepping technique,a novel adaptive H_∞controller is constructed. The proposed controller guarantees the effect from external disturbance to the system output in sense of L₂gain arbitrarily small.and the system states are asymptotically stable without disturbance.更多还原
