For a class of strict-feedback chaotic systems driven by a linear and neutrally stable exosystem with un-known parameters, the output regulation problem is considered. Based on the necessary condition to solve the output regulation problems of nonlinear systems, the problem of strict-feedback chaotic systems can be transformed into a stabilization problem. The virtual controllers are designed by adapting dynamic surface technology at the former n-1 steps, which can largely decrease the complexities of the design progress. The output regulation controller is de-signed by using the internal model theory, coupling with bonding adaptive theory at the nth step. By applying the Lyapunov stability theorem, it is proved that all the signals in the closed-loop error system are uniformly and ulti-mately bounded. The simulation results turn out that the control strategy is effective for the problems involved.
