| Abstract: | The disturbance rejection problem for nonlinear systems under external persistent disturbances is considered.Based on the principle of full-state linearization,the nonlinear disturbance rejection control law is designed in which the nonlinear control term cancels the open-loop nonlinearity.The optimal disturbance rejection control law is designed for the linearized system,in which the feedforward term compensates for the effect produced by the disturbance.Simulation examples demonstrate the designed controller can suppress the disturbance effectively suffered by the nonlinear system. |

| Keywords: | nonlinear systems full-state linearization disturbance rejection optimal control |
