Abstract

Brushless DC (BLDC) motors provide advantages in efficiency, reliability and performance that could replace other motors in a range of applications. Conventional controller suffers from some disturbance and the nonlinear of the BLDC motor. To overcome nonlinearity and disturbances problems, this paper proposes the speed control of BLDC with H∞ fuzzy controller based on LMI approach. The results show improvement in transient response and steady state error, including a stability criterion in terms of Lyapunov method can guarantee the stability of the nonlinear fuzzy system. Finally, the effectiveness of this approach is demonstrated through simulation results.
