Description
Summary:In this paper, the robust finite-time synchronization control and parameter identification problems for uncertain permanent magnet synchronous motor are discussed in detail. Based on finite-time control theory, by using adaptive control approach, a novel adaptive finite-time control scheme is proposed firstly. Then, a robust adaptive finite-time synchronization control method is developed depending on the terminal attractors with updating tuning parameters, which can not only guarantee the synchronization of permanent magnet synchronous motor with uncertain parameters in a shorter finite time, but also can guarantee these uncertain parameters to be identified effectively simultaneously. Finally, some simulation and comparison results are provided to demonstrate the effectiveness and usefulness of the developed results.
