Abstract :
Permanent magnet brushless DC (PMBLDC) motor exhibits nonlinear behavior due to its friction, inertial variation, saturation and nonlinear coupling between motor current and rotor speed. Such uncertain and time varying system dynamics entitle the auto tuning speed control strategy for PMBLDC motor. The self tuning speed control of PMBLDC motor is subject to stringent problems because the usual controllers are not robust against the inertial and load variations. This paper aims to design and implement a novel auto tuning controller which is robust against load and inertial variations. Tests were performed on the PMBLDC motor simulation model, which provided valuable practical experience to implement the proposed tuning technique.
