Multi-Objective Optimisation-based Robust H∞ Controller Design Approach for a Multi-Level DC-DC Voltage Regulator

In case an analytical approach to the selection of any weighting function is not possible, process usually a random and time-consuming process. robust H∞ control theory, scalar, time, or frequency-dependent functions main issue shape amplitude-frequency characteristic curve feedback controller. Therefore, we propose which utilises multi-objective grey wolf optimisation algorithm (MOGWO) obtain optimal performance in presence right half-plane zeros limited bandwidth constraints. A trade-off design flowchart proposed, providing Pareto solutions choose configuration The method structured by combining technique algorithm. effectiveness compared with non-convex single-objective heuristic like multi-verse (MVO), whale (WOA), (GWO). focus this track stabilise output voltage DC-DC converter external disturbances parameter uncertainties. optimised controllers are implemented using digital signal processor (DSP) on 200 W interleaved boost converter. simulation results experimental findings show that proposed provides supreme disturbance rejection along maintaining stability system.
