Multi-predictor scheme design for stabilizing first-order systems with significant delays

https://doi.org/10.58571/CNCA.AMCA.2025.054

Resumen: This paper introduces a control scheme for first-order systems with substantial time delays, grounded in a multipredictor approach. The proposed methodology employs multiple prediction models (sub-predictors) in conjunction with output injection to enhance the system’s stability and performance. Necessary and sufficient conditions ensuring system stability are provided, and a systematic procedure is developed to determine the minimum number of sub-predictors required to guarantee observer stability, thereby avoiding overly complex design structures. The obtained results substantiate the effectiveness of the proposed scheme in stabilizing systems with long delays, outperforming traditional control strategies. A simulation example is presented to validate the proposal.
