Abstract:

In order to reduce the influence of parameter perturbation, load disturbance, friction disturbance and other uncertain disturbances on the position synchronization accuracy of dual linear motors in H-type platform, a control method combining active disturbance rejection controller(ADRC) and fuzzy pi-sigma neural network synchronous compensator is proposed. In order to reduce the position tracking error of permanent magnet linear synchronous motor(PMLSM) servo system, active disturbance rejection technology is used to observe the unmodeled disturbance and external disturbance, and these disturbances are regarded as the “total disturbance” of the system, which can be compensated in real time. At the same time, aiming at the mechanical coupling between the two shafts and the dynamic parameter mismatch between the motors of the direct drive H-type platform, the fuzzy pi-sigma neural network synchronous compensator is used to reduce the synchronization error of the direct drive H-type platform. Finally, the simulation results show that the control strategy can effectively improve the tracking accuracy and synchronization accuracy of the direct drive H-type platform, and enhance the anti-interference performance of the system.
