description This paper provides a comprehensive performance analysis approach for Real‐Time Optimization (RTO) technologies, which incorporates systematic approaches to estimating bounds on the convergence behaviour and performance effects of on‐line experiments used by a given RTO approach. The performance analysis method is illustrated by an investigation of the conventional two‐phase approach and representative techniques drawn from the three main classes of perturbation‐based RTO methods which attempt to directly compensate for plant/model mismatch through adaptation. The proposed approach is applied to two simulation‐based case studies: a heat exchanger system and a continuous bioreactor. On présente dans cet article une méthode complète d'analyse de performance pour les technologies d'optimisation en temps réel (RTO), qui comporte des approches systématiques pour l'estimation des bornes de convergence et les effets de performance sur des expériences en ligne utilisées dans une approche RTO donnée. L'analyse de performance est illustrée par une étude de l'approche conventionnelle à deux phases et des techniques représentatives issues des trois catégories principales de méthodes RTO basées sur des perturbations et qui tentent de compenser directement l'incompatibilité usine/modèle par l'adaptation. La méthode proposée est appliquée à deux études de cas basées sur des simulations : un système d'échangeur de chaleur et un bioréacteur continu.
