Due to frequent external disturbances occurring in linear motors, especially in long-distance drive systems, traditional proportional-integral (PI) controllers cannot meet the requirements of dynamic performance and robustness capability. The active disturbance rejection controller (ADRC) has been widely adopted for its effectiveness in improving the disturbance immunity of motor drives. Nonetheless, conventional nonlinear ADRC (NLADRC) and linear ADRC (LADRC) have their own advantages, disadvantages, and specific application scopes in the disturbance range. To extend the application range and enhance the dynamic performance and anti-interference capability, a cascaded ADRC (CADRC) is proposed as the speed regulator, which integrates the linear extended state observer (LESO) and the nonlinear extended state observer (NLESO) to estimate the total disturbance. Then the stability and the performance indicators of the proposed CADRC are theoretically analyzed using the Routh-Hurwitz stability criterion and frequency-domain analysis. Finally, the feasibility and effectiveness of the control scheme are verified through simulations and experiments on a prototype of a linear flux-switching permanent magnet (LFSPM) motor.
