Non-conventional implementation of the speed controller applied to a brushless DC motor with trapezoidal back EMF

Intelligent control such as fuzzy logic controller (FLC) is one of non conventionnel controller due to the non-linearity features. FLC is high performance control of Permanent magnet brushless DC motor (BLDCM) in the industry. It has excellent transient and steady-state response and relatively simple structure. This paper focus to design these controller in Simulink and implemented in real time using the DS1104 DSP of dSPACE; As well, the 600 W inverter and our drive board are designed for driving the motor. The experimental results show that the FLC performs well in controlling the speed of the Permanent magnet brushless DC motor with satisfactory result
