This study presents a comparison between a well-known instantaneous reactive power (Q)-based model reference adaptive system (MRAS) (Q-MRAS) and a relatively new X-MRAS used for the speed estimation of induction motor drive without speed sensor from the stability point of view. Stability aspects and sensitivity analysis of both the schemes to machine parameters variation are examined. The instantaneous and steady-state values of Q are considered to develop the reference and adaptive models respectively for the former, whereas those of a fictitious quantity X (i.e. n*× i) are considered in the said models for the later. Non-computation of flux in these schemes leads to the satisfactory estimation of speed over a wide range maintaining the drive's stability in all the 4-quadrants. Both the Q-a n dX-MRAS are found to be dependent on the rotor resistance variation, whereas X-MRAS is also influenced by the stator resistance variation. A small signal stability study over a wide range of stator and rotor resistance variations is carried out to investigate the drive's stability in the low-speed region for both the MRAS schemes. Matlab/ Simulink is used to obtain the simulation results for the proposed study. Experimental results are obtained through a dSPACE-1104-based laboratory prototype.

“…FF current control, which includes single-pulse control of the inverter, is employed to minimize the switching loss over a wide speed range [3] [4]. The current control mode is switched from the PI current control that the sufficient voltage margin is needed for the current control to the FF current control when the modulation ratio is reached to the over modulation region.…”

Feed-forward current control, which employs a single-pulse mode of inverters over a wide speed range, is applied in inertial load drive applications such as electric vehicles and electric railway vehicles. It is necessary to identify both primary and secondary motor parameters to realize sophisticated torque control in the feed-forward current control region, wherein the current controller cannot compensate for motor parameter errors. An online auto-tuning method that is based on the fundamental components of motor voltages during acceleration with an inertial load is proposed in this study. The convergence of the proposed auto-tuning is discussed, and a calculation method for correction gains is proposed to compensate for the motor parameters. The proposed method is verified via numerical simulation and experiments with a 750 W induction motor and an inertial load.
