Abstract
In this article, we propose an identification-based control scheme for a DC Brushless motor drive. The identification scheme is based on the algebraic identification method which allows for fast parameter identification whose, on line, computed values are used in canceling out the nonlinearities of the system dynamics thus reducing the control problem to that of a pure integration system. The control scheme consists of two stages: the first one is a outer loop current control which generates the required reference signal for the inner loop velocity control. A Generalized Proportional Integral control scheme is used in both loops, obtaining accurate, feasible, results as demonstrated by numerical simulations.
