A Single-Loop Framework for the Reliability-Based Control Co-Design Problem in the Dynamic System

When solving the control co-design (CCD) problem using simultaneous strategy in a deterministic manner, uncertainty stemming from stochastic design variables is ignored, and might have negative influence on performance of dynamic system. In attempting to overcome undesirable effect uncertainty, this research investigates reliability-based (RB-CCD) presents single-loop framework for RB-CCD based modified model approach (SLA). Specifically, deduced by introducing additional equality constraints (state equations algebraic constraints) so as transform probabilistic into inequality constraints. Meanwhile, enhance solution efficiency, SLA transforms an equivalent CCD incorporating approximate reliability information optimization. Finally, numerical example engineering are implemented verify feasibility effectiveness optimization framework. The results demonstrate that suggested dramatically improves system, significantly increases efficiency without compromising accuracy.
