One-Cycle Control (OCC), as a unified constant-frequency integration control strategy for current control of brushless dc (BLDC) motor drive is presented in this paper. Employing the one-cycle control strategy reduces high frequency torque ripple of conventional hysteresis current controllers that leads to lower acoustic noise and vibration of the drive. Moreover, to enhance reliability and reduce total cost of the drive, an improved low-cost rotor position estimation strategy is implemented. It is based on detection of the true back-EMF zero-crossing points that can be directly extracted by detection of voltage between phase terminal and midpoint of dc link without motor neutral point voltage. Total operations of OCC strategy and sensorless method are realized by a low-cost general-purpose AVR microcontroller (Atmega8) that leads to a low-cost, high performance sensorless BLDC motor drive. Computer simulations using Matlab simulator, have been presented to show characteristics of this solution. Experimental results with a 230 W, 14 poles BLDC motor, show improved behavior of developed sensorless BLDC drive in both steady-state, and transient situations.

Traditional BLDC motor drives use voltage source inverters (VSI) that utilize PWM and hysteresis hard switching methods. It leads to generate switching losses and need to use of large heat sinks. VSIs are costly because of low reliability and need to large DC link capacitor. Moreover, common control methods such as hysteresis current control can create variable range of high frequency noises. This paper overcomes the problems of VSIs and reduces the volume and cost, by using current source inverter (CSI) which replaces an inductor instead of DC link capacitors. Also, to solve the problems of hysteresis control method, one-cycle control (OCC) technique has been used for soft switching of the inverter. Moreover, to reduce the difficulties and cost of installing electromechanical sensors in BLDC motors an appropriate method for rotor position estimation has been presented. Simulation results in Matlab/Simulink verify the effectiveness of OCC-based control of CSI-BLDC motor drive comparing to hysteresis-based VSI-BLDC motor drive.

This paper provides a technical review of position and speed sensorless methods for controlling Brushless Direct Current (BLDC) motor drives, including the background analysis using sensors, limitations and advances. The performance and reliability of BLDC motor drivers have been improved because the conventional control and sensing techniques have been improved through sensorless technology. Then, in this paper sensorless advances are reviewed and recent developments in this area are introduced with their inherent advantages and drawbacks, including the analysis of practical implementation issues and applications. The study includes a deep overview of state-of-the-art back-EMF sensing methods, which includes Terminal Voltage Sensing, Third Harmonic Voltage Integration, Terminal Current Sensing, Back-EMF Integration and PWM strategies. Also, the most relevant techniques based on estimation and models are briefly analysed, such as Sliding-mode Observer, Extended Kalman Filter, Model Reference Adaptive System, Adaptive observers (Full-order and Pseudoreduced-order) and Artificial Neural Networks.

Control methods for the pulsation of torque reduction for the surface-mounted permanent magnet motors are discussed. The pulsation torque is a consequence of the non-sinusoidal flux distribution and due to interaction of the rotor's permanent magnets with the changing stator reluctance. The proposed control method is an estimator based. To ensure parameter convergence the Lyapunov direct method is used in the estimator design for the flux Fourier coefficients. A novel nonlinear torque controller based on the flux/torque estimate is introduced to reduce the influence of the flux harmonics. The influence of the cogging torque is considerably reduced at lower motor speed using the internal model principle and adaptive feedforward compensation technique. An overall control scheme and experimental results are also presented

With ever-increasing concerns on our environment, there is a fast growing interest in electric vehicles (EVs) and hybrid EVs (HEVs) from automakers, governments, and customers. As electric drives are the core of both EVs and HEVs, it is a pressing need for researchers to develop advanced electric-drive systems. In this paper, an overview of permanent-magnet (PM) brushless (BL) drives for EVs and HEVs is presented, with emphasis on machine topologies, drive operations, and control strategies. Then, three major research directions of the PM BL drive systems are elaborated, namely, the magnetic-geared outer-rotor PM BL drive system, the PM BL integrated starter-generator system, and the PM BL electric variable-transmission system.

Working with the subject of sensorless motor control requires an understanding of several topical areas; this report presents an understanding that was gained during this research work. The fundamentals of electric motors (particularly brushless motors) are developed from first principles and the basic models are discussed. The theory of sinusoidal synchronous motors is reviewed (phasor analysis of the single phase equivalent circuit). The concept of a complex space vector is introduced and developed using a working knowledge of the sinusoidal synchronous motor. This leads to the presentation of the space vector model of the permanent magnet synchronous motor, in both the stationary and rotor reference frames. An overview of the operation of three-phase voltage source inverters is given, followed by an explanation of space vector modulation and its relationship to regular sinusoidal pulse width modulation. Torque control of the permanent magnet synchronous machine is reviewed in several reference frames and then rotor-flux-field-oriented-control is explained. Finally, some schemes for sensorless operation are discussed. ICE Corporation Master of Science Masters Department of Electrical and Computer Engineering James E. DeVault

The application of direct torque control (DTC) to brushless AC drives (BLAC) has been investigated extensively. This work describes its application to brushless DC drives (BLDC), and highlights the essential differences in its implementation, in relation to the torque estimation and the representation of the inverter voltage space vectors. Simulated and experimental results are presented, and it is shown that, compared with conventional current control, instantaneous torque control results in reduced torque ripple and a faster torque response.

Torque-ripple control of the brushless DC motor has been the main issue of the servo drive systems in which the speed fluctuation, vibration, and acoustic noise should be minimized. Most methods for suppressing the torque ripples require Fourier series analysis and either iterative or least-mean-square minimization. In this paper, a novel approach to achieve ripple-free torque control with maximum efficiency based on the d-q-0 reference frame is presented. The proposed method optimizes the reference phase current waveforms which include the case of three-phase unbalanced conditions. As a result, the proposed approach provides a simple way to obtain optimal motor excitation currents. The validity and practical applications of the proposed control scheme are verified through the simulations and experimental results

Permanent magnet machines with trapezoidal back EMF waveform have been the subject of several papers in the past. The simplicity in control and the absence of an absolute position sensor makes this type of motor very attractive. Idealized analysis of such a machine is simple and will result in trapezoidal or square wave back EMF waveforms depending on the assumptions made. In the case of an idealized quasi-square wave current excitation, a ripple-free torque will be obtained. The actual back EMF waveform of these machines depends on the flux density and the conductor distributions. This in turn is a function of the magnet magnetization and the stator tooth and slot structure. In applications where a fairly smooth torque is needed, these machines are made with either the stator slots or the rotor magnets skewed by one slot. This paper deals with the analysis of the back EMF waveform and of the torque ripple waveform of such a machine when the stator slots or rotor magnets are skewed by one slot. The analysis takes into consideration the actual stator conductor distribution and the effect of magnet magnetization on the back EMF waveform. An empirical formula is developed for the magnet flux density distribution which could be used for various magnetization conditions of the magnet. Experimental results are included to confirm the analytical results
