Methods and Tools for Robust Optimal Control of Batch Chromatographic Separation Processes
This contribution concerns the development of generic methods and tools for robust optimal control of high-pressure liquid chromatographic separation processes. The proposed methodology exploits a deterministic robust formulation, that employs a linearization of the uncertainty set, based on Lyapunov differential equations to generate optimal elution trajectories in the presence of uncertainty....
متن کاملOpen-loop and closed-loop robust optimal control of batch processes using distributional and worst-case analysis
The recognition that optimal control trajectories for batch processes can be highly sensitive to model uncertainties has motivated the development of methods for explicitly addressing robustness during batch processes. This study explores the incorporation of robust performance analysis into open-loop and closed-loop optimal control design. Several types of robust performance objectives are inv...
متن کاملDistributed Loop-shaping for Iterative Control of Batch Processes
The idea of iterative control of batch processes has been discussed in the literature for some time. Many related concepts have been published under the names iterative control, learning control, run-to-run control, and others. This article uses the name iterative learning control (ILC). The main idea of ILC is illustrated in Fig. 1. An ILC controller provides feedforward control input to a pla...
متن کاملNumerical Solution of Optimal Control Problems by Direct Collocation
By an appropriate discretization of control and state variables, a constrained optimal control problem is transformed into a finite dimensional nonlinear program which can be solved by standard SQP-methods [10]. Convergence properties of the discretization are derived. From a solution of this method known as direct collocation, these properties are used to obtain reliable estimates of adjoint v...
متن کاملLifted collocation integrators for direct optimal control in ACADO toolkit
This paper presents a class of efficient Newton-type algorithms for solving the nonlinear programs (NLPs) arising from applying a direct collocation approach to continuous time optimal control. The idea is based on an implicit lifting technique including a condensing and expansion step, such that the structure of each subproblem corresponds to that of the multiple shooting method for direct opt...
