AbstractThe paper considers the control problem for uncertain nonlinear systems with unknown control input gain. Based on the information of control direction rather than the nominal value of control input gain, a new active disturbance rejection control design is proposed. In the proposed design, the extended state observer (ESO) is constructed to estimate the total disturbance containing the uncertainty of control input. Via the estimations from ESO, the control input is generated by a designed dynamical system, which can force the actual input to track the ideal input. Moreover, for a wide class of nonlinear uncertainties, the transient performance of the proposed design is investigated. The theoretical results show that the tracking and estimating errors, as well as the difference between the actual and ideal inputs, can be sufficiently small by tuning the parameter of ESO despite various uncertainties. The experiment of a permanent magnet linear synchronous motor servo system illustrates the effectiveness of the proposed design.
