“…As future extension of this study, other control schemes can be used to control the pendulum system [15][16][17][18][19][20], or one can use modern optimization techniques to tune the design parameters of SC and SMC towards their improvement [21][22][23][24][25].…”

This study presents a performance comparison between a synergetic controller (SC) and a sliding mode controller (SMC) applied to a pendulum system. Initially, the mathematical model of the pendulum system is established. Subsequently, the design of both synergetic and sliding mode controls is elaborated, leading to the development of control laws for the proposed controllers. The effectiveness of the pendulum system controlled by SC and SMC has been validated through numerical simulations. These simulations revealed that the control signal exhibits chattering behaviour in the case of SMC, while this phenomenon is absent with the SC, demonstrating a distinct difference in performance between the two control systems.

“…High-voltage (HV) converters are used in motor drives [1], static VAR compensators [2], renewable energy systems [3], [4], high-voltage direct current (HVDC) transmission and other similar applications [5][6][7]. The traditional single-phase inverter generates two or threelevels in the output signal, while MLIs can create multilevels in the output signal.…”

Cascaded H-bridge multilevel inverters (CHB-MLI) are employed in a variety of medium/high power applications. These inverters are known to inject unwanted harmonics into the grid, which negatively affects the grid and connected loads. CHB-MLI topology can reduce many of these harmonics by producing multiple output voltage levels and improves the fundamental component using a suitable modulation technique. However, the CHB-MLI topology configuration requires multiple isolated input sources which must be balanced either with the modulation technique or with an additional method. This paper analyzes multi-carrier pulse width modulation (MC-PWM) techniques for CHB-MLIs. In this study, two basic configurations of CHB-MLI symmetrical and asymmetrical are reviewed, followed by their mathematical analysis. Also, this paper analyses multicarrier based sinusoidal pulse width modulation (MC-SPWM) and multi-carrier based third-harmonic injected pulse width modulation (MC-THIPWM) techniques with phase-shifted (PS) and level-shifted (LS) carrier arrangements for the CHB-MLI. Moreover, a simulation study has been conducted using MATLAB Simulink to analyze the performance of MC-PWM techniques for the symmetrical and asymmetrical type CHB-MLIs. The 7-level and 9-level CHB-MLIs were evaluated for the stated MC-PWM techniques in terms of harmonics and fundamental components. In addition, discharging current of all input sources was checked to verify the ability of all MC-PWM techniques to balance all input sources.

The work in this paper presents the performance analysis of the reduced component count converter which is the 5-Level Active Neutral Point Converter (5LANPC). This 5-level converter has been configured by stacking the traditional 3-Level Neutral Point Converter with the Flying Capacitor converter. Two types of control algorithms were considered and compared to explore the performance of the 5LANPC. The first algorithm was based on the Phase-Disposition-Pulse Width Modulation (PD-PWM), while the second one was based on the Alternate Phase Opposition Disposition-Pulse Width Modulation (APOD-PWM). These algorithms are used to determine the required voltage level and according to the required level the state of the switches is selected through a simplified voltage balance algorithm. This voltage balance algorithm deals with the redundant switching states to maintain the voltages of the 5LANPC capacitors at a specified level. The comparison between these two modulation strategies was performed by simulation based on MATLAB/Simulink package. Simulation results showed compelling outcomes involving the two techniques concerning the voltage and current characteristics, as well as the equilibrium in the capacitor voltages. By comparing the simulation results, it was found that the performance of the system is relatively better using the PD-PWM strategy.
