The paper presents modelling, control architecture, analysis and design of digital compensators for single feedback-loop voltage mode control as well as two feedback-loop average current mode control and peak current mode control of current controlled DC-DC Buck converter operating in continuous conduction mode with output current as control variable. The compensators are derived using digital redesign approach, simulated on MATLAB, implemented as control algorithms on Texas Instruments' 32-bit TMS320F28069M microcontroller platform, and experimentally validated by testing with a laboratory prototype of current controlled Buck converter. Simulation and experimental results are discussed, compared and evaluated for converter output current performance in tracking reference current signal as well as in regulation against input voltage and load disturbances. Salient features of each control technique are identified and described to determine its suitability in applications of DC-DC converters requiring controlled output current.

For the driving of the permanent magnet synchronous motor (PMSM), a method for rotor position and speed estimates is presented in this research. The model reference adaptive system (MRAS) technology combined with stator feed-forward voltage estimation (FFVE) is the proposed approach. The suggested approach continuously updates the FFVE model while also estimating machine parameters for a closed-loop drive system like rotor flux linkage and stator resistance. In order to enhance the system's overall dynamics and stability and to get rid of transient oscillation in speed estimate, this study also includes a phase-lock loop (PLL) speed estimation approach. Analysed and experimentally validated under various operating situations, the proposed method's superiority in terms of the steady-state and dynamic performance of sensorless control of PMSM drives is examined.

This article proposes a novel concept of improving the harmonic profile in multilevel inverter (MLI) using the ratio rule method. THD minimisation in MLI using selective harmonic elimination (SHE) approach using various optimisation techniques is covered in several literatures followed by further THD reduction using alterable DC sources. The methods discussed in various literature use rigorous derivations of constants that are used for further reduction of THD profile. This article introduces the ratio rule method for further reduction of the THD in multilevel inverter, after optimisation process using various algorithms. The proposed study is conducted using the SHE approach for THD reduction using genetic algorithm followed by further THD reduction using ratio rule. A three-phase seven-level cascaded H-bridge inverter is simulated in MATLAB as well as its hardware is implemented for deriving the proof of proposed concept. It is found that the proposed method is faster, easier and produces a maximum of 12.60% reduction in THD profile.

This article proposes investigation on harmonic profile improvement using a novel fitness function in the multiphase multilevel inverter. For the proposed study in this paper, three-phase, seven-level cascaded H-bridge (CHB) multilevel inverter (MLI) is considered. Modulation of the stepped waveform output of the MLI is done using selective harmonic elimination (SHE) method. Many algorithms are proposed for solving the set of nonlinear transcendental trigonometric equations for SHE methods. Teaching learning-based optimisation (TLBO) algorithm is a parameter less optimisation technique. Due to the lack of controlling parameters, the proposed algorithm is most robust among the family of artificial intelligence (AI) techniques. In this paper, an investigation is carried out on a novel fitness function proposed for controlling total harmonic distortion (THD) for the proposed inverter. It is observed that the proposed fitness function improves THD profile below IEEE standards. It is also observed that THD profile obtained through this method is far better than THD profile obtained through various proposed methods so far. The results of THD profile from the MATLAB Simulink simulations are verified experimentally using seven-level three-phase hardware controlled by Arduino MEGA 2560 low-cost controller.
本文提出了利用一种新的适应度函数改善多相多电平逆变器谐波轮廓的研究。本文研究的是三相七电平级联h桥(CHB)多电平逆变器(MLI)。采用选择性谐波消除(SHE)方法对MLI的阶跃波形输出进行调制。在SHE方法中，提出了许多求解非线性超越三角方程组的算法。基于教学的优化算法(TLBO)是一种无参数优化技术。由于缺乏控制参数，该算法在人工智能(AI)技术家族中是最鲁棒的。本文研究了一种控制逆变器总谐波失真(THD)的适应度函数。观察到所提出的适应度函数改善了低于IEEE标准的THD曲线。还观察到，通过该方法获得的THD剖面远优于目前提出的各种方法获得的THD剖面。在Arduino MEGA 2560低成本控制器控制的七电平三相硬件上，对MATLAB Simulink仿真所得的THD轮廓进行了实验验证。
