In the pharmaceutical industry, it is common to determine the maximum allowable set of uncertain parameters—called the design space—that guarantees that the product quality attributes obtained by a manufacturing process are within specified limits. In industrial practice, design spaces are constructed without considering the effects of process dynamics or feedback control, which results in poor characterization...
The selection of the control structure, which is a specification of the interconnection of measurements, exogenous inputs, and manipulated variables, is a critical step in the design of a control system. This paper presents a general internal model control structure with multiple degrees-of-freedom in which each controller can be independently designed for stable systems. The control system is shown...
A computationally efficient approach is presented that quantifies the influence of parameter uncertainties on the states and outputs of finite-time control trajectories for nonlinear systems, based on the approximate representation of the model via polynomial chaos expansion. The approach is suitable for studying the uncertainty propagation in open-loop or closed-loop systems. A quantitative and qualitative...
