The main bottleneck in using optimization at the industrial level is the presence of uncertainty in the form of model mismatch and disturbances. The way uncertainty can be handled constitutes the subject of this series of two papers. The first part dealt with the characterization of the nominal solution and proposed an approach to separate the(More)
Process measurements can be used in an optimization framework to compensate the effects of run-time uncertainty. Among the various options for input adap-tion, a promising approach consists of directly enforcing the Necessary Conditions of Optimality (NCO) that include two parts: the active constraints and the sensitivities. In this paper, the variations of(More)
The optimization of batch processes has attracted attention in recent years because, in the face of growing competition, it is a natural choice for reducing production costs, improving product quality, meeting safety requirements and environmental regulations. This paper starts with a brief overview of the analytical and numerical tools that are available(More)
Challenges in real-time process optimization mainly arise from the inability to build and adapt accurate models for complex physico-chemical processes. This paper surveys different ways of using measurements to compensate for model uncertainty in the context of process optimization. Three approaches can be distinguished according to the quantities that are(More)

However, in this article it is shown that not all manipulators possess this property. The class of serial robot manipulators with bounded(More)
Maximizing the yield of a second-order reaction by manipulating the inlet flow rate is considered in both the isoperibolic and isothermal modes. For safety considerations, constraints on (i) the amount of heat produced, and (ii) the temperature under cooling failure are imposed. The optimal solution is discontinuous and is first obtained numerically.(More)
Run-to-run control has been applied to several traditional batch processes in the chemical industry. The 24-h cycle of eating meals, measuring blood glucose concentrations, and delivering the correct insulin bolus, with the goal of achieving the optimal blood glucose profile, can be viewed in the same spirit as traditional batch processes such as emulsion(More)
