The velocity loop, as the intermediate loop of the
brushless direct current motor (BLDCM) servo system,
has the direct
effect on the control precision and response speed.
Due to the closed-loop transfer function of velocity
loop is related to the
intermediate controller and its difficult to convert
the transfer function of velocity loop to state space
dynamical equation when the
structure of controller has not been determined. By
focusing on the block diagram of the typical three-
loops structure and considering
the coupling effect between the position loop and
velocity loop, then simplifying the velocity loop, a
simple, effective and practical
adaptive generalized predictive controller, which is
based on prediction and optimization of multi-step
rolling, is introduced in
brushless DC motor application. Finally, simulation
results show the validity of the method.
