Research on improved model-free adaptive control algorithm to suppress the influence of disturbances

摘要

The model-free adaptive control (MFAC) algorithm is the key point in the control. It is significance to deeply study on MFAC. Aiming to suppress the influence of disturbances, an improved hybrid model-free adaptive control algorithms is proposed based on the MFAC with a decreasing gain and MFAC with a filter. Considering the advantages and disadvantages of two MFAC algorithms, the algorithms proposed are combined two methods and introduced threshold switching. Simulation results verify the effectiveness of the algorithms proposed.
