BLDC motors are characterized by electronic commutation, which is performed by using an electric three-phase inverter. The direct control system of the BLDC motor consists of double loops; including the inner-loop for current regulating and outer-loop for speed control. The operation of the current controller requires feedback of motor currents; the conventional current controller uses two current sensors on the ac side of the inverter to measure the currents of two phases, while the third current would be accordingly calculated. These two sensors should have the same characteristics, to achieve balanced current measurements. It should be noted that the sensitivity of these sensors changes with time. In the case of one sensor fails, both of them must be replaced. To overcome this problem, it is preferable to use one sensor instead of two. The proposed control system is based on a deadbeat predictive controller, which is used to regulate the DC current of the BLDC motor. Such a controller can be considered as digital controller mode, which has fast response, high precision and can be easily implemented with microprocessor. The proposed control system has been simulated using Matlab software, and the system is tested at a different operating condition such as low speed and high speed.

“…Good dynamic properties of deadbeat control, like low steady-state error, quick rise and settling time, make it a convenient and simple choice in various process controls [1][2][3][4][5][6]. Deadbeat control technique in comparison to other modern control techniques (e.g resonant control, repetitive control) is simple, quick and achieves the steady state in minimum number of time steps.…”

This research comprehensively investigates the effect of uncertain time delay on performance of the deadbeat control. A solution based on a non-integer order Smith predictor has been proposed and analyzed to compensate uncertain time delays occurring in a stable closed loop system. Deadbeat control has been widely and conveniently used in the control of linear and non-linear systems. However, this control technique is severely sensitive to unmodeled dynamics and parameter uncertainties. Thus the performance of system may deviate significantly and hence lead to instability in practical cases. Time delay in a closed loop control system is a common source of unmodeled dynamics, which severely deteriorates control accuracy and results in reduced stability margin of the deadbeat control system. Physical system considered in this research work is a single-phase inverter. The simulation results indicate that the Smith predictor based deadbeat control scheme offers accurate time delay compensations and thus enhances the robustness and stability margin. Application example comprehensively illustrates effectiveness of the proposed control technique.

“…It has been noted in [3] that if the un-commutated phase current can be fixed during the commutation period, then the torque ripple can be eliminated under certain assumptions. The main assumption is to consider that the phase back-emf (electromotive force) signals are ideal and constant during the commutation period.…”

In this paper, a control strategy for the current loop of brushless DC motor (BLDCM) drives is proposed to reduce the commutation torque ripple. The proposed method consists of two different controllers based on dead-beat structure. Two different electrical model of BLDCM for conducting and commutation periods are considered by the controllers that are switched in conducting and commutation periods. In addition, a model based prediction is utilized to predict the beginning and ending of the commutation periods. Then, this information is used to modify the reference phase voltages in order to reduce commutation torque ripple. The characteristics of the proposed controller are evaluated by numerical simulations and satisfactory results are obtained.
