Extended State-Dependent Differential Riccati Equation (ESDDRE) Controller Design for a Chemical Plug-Flow Reactor via Time-Delay Partial Differential Equation

Liavoli, Fariba Bouzari; Fakharian, Ahmad; Khaloozadeh, Hamid

2024 Iranian Journal of Science and Technology Transactions of Electrical Engineering

doi:10.1007/s40998-024-00720-2

Numerous processes in chemical and biological engineering make use of tubular reactors. A particular kind of tubular reactor was known as a chemical plug-flow reactor (PFR) when there is no diffusion term. This paper offers a nonlinear controller for a non-isothermal PFR governed by time-delay...

A Reduced Switch Count Single-Source Seven-Level Switched-Capacitor Boost Multilevel Inverter with Extendibility

Dolati, Hadi; Babaei, Ebrahim; Ebrahimzade, Soghra

2024 Iranian Journal of Science and Technology Transactions of Electrical Engineering

doi:10.1007/s40998-024-00708-y

A switched-capacitor-based multilevel inverter (MLI) topology is given in this study. The suggested MLI employs fewer power switches and has an extendable configuration that allows it to increase the number of output voltage levels while using a single DC source. To produce gate pulses, the...

A Perceptive SPS-LPDP Controller for Increasing the Power Quality Performance of Grid Integrated Symmetric Switching Multilevel Inverter

Srinivasan, S.; Srinivasa Rao, G.; Muthubalaji, S.

2024 Iranian Journal of Science and Technology Transactions of Electrical Engineering

doi:10.1007/s40998-024-00719-9

Designing an efficient and advanced controlling technique for improving the power quality of grid integrated multilevel inverters is one of the challenging and demanding tasks in recent days. Because reduced Total Harmonic Distortions (THD), voltage sag, swell, and other power quality issues have...
