In this paper, a novel tuning technique for the current and speed controllers of the Brushless DC (BLDC) motor derive system is presented. The parameters of PI controllers in the inner current control loop and outer speed control loop which vary with the operating conditions such as variation of temperature and saturation phenomena or load torque changing of the drive are adjusted in order to m...

Model Based Control (MBC) is one of the energy optimal controllers used in vector-controlled Induction Motor (IM) to control the excitation of the motor in accordance with the torque and speed. MBC improves the performance of the motor, but it produces ripples in the torque and speed. This paper investigates the opportunity for improving dynamic performance in a three-phase IM operating with MB...

In this paper, an adaptive nonlinear controller is designed for rotor Surface Permanent Magnet Synchronous Motor (SPMSM) drive on the basis of Input-Output Feedback Control (IOFC), and Recursive Least Square (RLS) method. The RLS estimator detects the motor electromechanical parameters, including the motor iron loss resistance online. Moreover, a Sliding-Mode (SM) observer is developed for onli...
