“…Inside the PWM block, a dead time block was integrated in. Its function was to allow the inverter arm switches to not operate together, ensuring that a key can open before another closes by changing the block's parameters [27]. The full parameterisation of this block is presented in Fig.…”

Modern control systems’ dependability, safety and efficiency have all been improved by studying fault-tolerant control systems (FTCS). FTCS techniques can typically be active or passive controls. The fault detection and diagnosis (FDD) method is used in this study’s active control branch to identify probable faults that could develop in the speed Hall sensors of brushless DC motors (BLDC). FDD methodologies can be categorised into two types, depending on the available data and the process involved: model-based methods and data-based methods. The proposed approach in this study explores the implementation of the Luenberger observer methodology as part of the model-based approach. The chosen methodology was practically implemented and subjected to experimental evaluation. The proposed observer relies on the residual signal, which displays the difference between the plant’s observed and estimated speed signals and serves as a failure alert for the entire system. Given the increasing demand for BLDC motors in various industrial control applications, including medical fields, automation and robotics, this particular motor was selected as a benchmark to thoroughly evaluate and validate the proposed method. The primary contribution of this paper lies in the real-time application of model-based sensor fault detection methods to BLDC motors. The efficiency of the suggested method is showcased through extensive MATLAB simulations, where the obtained results confirm the successful detection of faults with a high level of responsiveness. As a result, the project was successfully implemented in real-time, and the experimental results exhibited a close correlation with the simulated outcomes. This consistency between simulation and practical implementation validates the accuracy and reliability of the proposed methodology for detecting faults in the BLDC motor speed sensor. The results underscore the heightened reliability and safety attained by promptly and accurately detecting sensor faults during the operation of the motor.

“…Consequently, the switching losses and current harmonics are minimized as a result of applied switching sequence which presents one switches during of switching mode switches. The switching time of SVPWM depends on the time period (T1, T2, and T0) as given in equations (9, 10, and 11) for each sector [18]. level neutral point clamped converter operation comprised of three switching status (Positive, Negative, and Zero), thereby this inverter is called three level NPC inverter.…”

Unbalanced input source voltages generate extra current harmonics in addition to non-linear loads which distorts the power quality in the entire power systems. Three-phase multi-level neutral point clamped (NPC) converter based shunt active harmonic filter (SAHF) are used as a solution to overcome problems due to current harmonics. In this work, synchronous reference frame (d-q) algorithm is selected to detect the harmonic current components, Proportional-integral (PI) controller is utilized to ameliorate the storage of energy in the dc-link capacitor and the multilevel space vector pulse width modulation (MSVPWM) strategy determines the switching pulses of NPC inverter. Under balanced input supply voltages condition, the proposed MSVPWM achieved a mitigation of source current THD of 3.58 % as compared to 28.57 % prior to compensation on non-linear load. Furthermore, the MSVPWM technique was compared with and without compensation under unbalanced input source voltages and the results shows that the proposed method achieved reduction in source current THD of 3.96 % as compared to 29.76 % after and before compensation respectively. The proposed MSVPWM based-SAPF model was also compared with conventional SVPWM under balanced and unbalanced input supply voltages conditions. The results show that MSVPWM performed better than CSVPWM. The simulated results obtained by MATLAB/SIMULINK power system environment. All the results for the presented work are within IEEE-519 harmonics standard with non-linear loads under balanced and unbalanced voltages condition.
