Abstract EN
An electromagnetic linear actuator (EMLA) has a promising application in direct motion control.
However, ELMA will inevitably inherit uncertainties in the face of load changes, system parameter perturbation, and inherent system nonlinearities, all of which constitute disturbances adversely affecting the precision and adaptability of the control system.
A model-free adaptive control (MFAC) strategy based on full form dynamic linearization (FFDL) was proposed to reduce the sensitivity of the control system to the disturbances.
An adaptive control of direct drive servo valve was achieved based on the online interaction of characteristic parameters and control algorithms.
The feasibility and precision of the proposed algorithm were verified through simulation and experimental results.
The results show that the proposed algorithm could achieve adaptive adjustment of the servo valve response at different openings of 0-3 mm without changing control parameters, with the response time controlled within 10ms and steady state error less than 0.04mm.
Furthermore, the proposed algorithm had better robustness and capacity of resisting disturbance.
