The invention discloses a linear motor active disturbance rejection control design method based on a Taylor tracking differentiator. Firstly, a Taylor tracking differentiator is designed by using feedback displacement information to estimate speed information, then a minimum-order extended state observer is designed by using the speed information to estimate interference on the linear motor, and aclosed-loop feedback controller selects PD control with feedforward compensation, so that limited bandwidth resources of the system are fully utilized, A system state and interference estimation scheme is reasonably designed, and the servo tracking precision of the linear motor is effectively improved.
