“…Derivation may lead to significant computational error due to switching noises. Similar attempts have been presented in [26,27] where back-EMF components and in rotating dq reference frame have been estimated by the same way. To avoid errors and problems due to derivation, some researches have been suggested using of phase-locked loop (PLL) to calculate motor speed from estimated position that actually increases the order of dynamic equations of the observer [24,28].…”

Nowadays, due to excellent advantages of permanent magnet brushless (PMBL) motors such as high efficiency and high torque/power density, they are used in many industrial and variable-speed electrical drives applications. If the fabricated PMBL motor has neither ideal sinusoidal nor ideal trapezoidal back-EMF voltages, it is named nonideal (or nonsinusoidal) PMBL motor. Employing conventional control strategies of PMSMs and BLDCMs lowers the efficiency and leads to unwanted torque ripple, vibration, and acoustic noises. Moreover, in many applications to reduce the cost and enhance the reliability of drive, sensorless control techniques are used. This paper proposes a novel sensorless control for a nonsinusoidal PMBL motor with minimum torque ripple. To develop smooth torque, the selected torque harmonic elimination strategy is employed. Furthermore, to estimate the rotor position and speed, a novel full-order sliding mode observer is designed. Proposed observer estimates the position and speed of motor from standstill to final speed. The proposed observer is robust to uncertainty of harmonic contents in phase back-EMF voltage and able to run the motor from standstill with closed-loop control scheme. The capabilities of torque ripple minimization and sensorless strategies are demonstrated with some simulations.

“…This estimation technique is very important because the quality of the estimation directly impacts the performance of the overall control scheme. The majority of the previous techniques used sliding mode observers (SMOs) because they are robust to noise and parameter uncertainties [20][21][22][23][24][25][26][27][28]. Reduced order observers have been also used due to their computational efficiency and simpler structure [29].…”

“…The most popular estimation technique of the back‐EMF signals is theSMO technique because of its many advantages including good robustness to parameter uncertainty and variation, and low computational complexity, which in turn leads to fast convergence and dynamic response [26, 27]. The SMO technique uses currents and voltages expressed in the (

In this paper, a sensorless hybrid control scheme for brushless DC (BLDC) motors for use in multirotor aerial vehicles is introduced. In such applications the control scheme must satisfy high performance demands for a wide range of rotor speeds and must be robust to motor parameter uncertainties and measurement noise. The proposed controller combines Field-Oriented Control (FOC) and Direct Torque Control (DTC) techniques to take benefit of the advantages offered by each of these techniques individually. Simulation results demonstrate the effectiveness of the proposed control scheme over a wide range of rotor speeds as well as good robustness against parameter uncertainties within −5.. + 10% for inductance and −5.. + 5% for resistance parameters. The proposed hybrid controller is robust also against noise in voltage and current measurements. In order to verify the results from simulation, the proposed hybrid controller is implemented in hardware using the TI C2000 Piccolo Launchpad and TI BOOSTXL-DRV8305EVM BoosterPack. Testing is done with a Bull Running motor typically used in aerial drones. Testing experiments demonstrate that the hybrid controller reduces the rotor speed ripple when compared to DTC while operating in steady-state mode and decreases the response time to desired speed changes when compared to FOC.

“…The drawbacks of EKF are: noise influence, complicated configuration, and computation implementation adversity. In contrast, sliding mode observers' advantages, such as: being appropriate for piecemeal designing, being suitable for non-smooth systems, having firmness against parameters variation, converging in the shortest possible time, and reducing the observation error, has made it an efficient popular method [24]. Therefore, sliding mode observer is employed in the current study.…”

This paper proposes a method for direct torque control of Brushless DC (BLDC) motors. Evaluating the trapezium of back-EMF is needed, and is done via a sliding mode observer employing just one measurement of stator current. The effect of the proposed estimation algorithm is reducing the impact of switching noise and consequently eliminating the required filter. Furthermore, to overcome the uncertainties related to BLDC motors, Recursive Least Square (RLS) is regarded as a real-time estimator of inertia and viscous damping coefficients of the BLDC motor. By substituting the estimated load torque in mechanical dynamic equations, the rotor speed can be calculated. Also, to increase the robustness and decrease the rise time of the system, Modified Model Reference Adaptive System (MMRAS) is applied in order to design a new speed controller. Simulation results confirm the validity of this recommended method. Index Terms-Brushless DC Motor, Direct Torque Control, Model Reference Adaptive System, Sliding Mode Observer
