【Abstract】 The problem of adaptive H_∞ control was addressed for a class of nonlinearly parameterized systems with unknown virtual control coefficients.Using parameter separation and Backstepping technique,a novel adaptive H∞ controller was constructed.The proposed controller guaranteed the effect from external disturbance to the system output in sense of L2 gain arbitrarily small.And the system states were asymptotically stable without disturbance.Simulation results were also given to illustrate correctness of the main results.更多还原
