Use of piecewise linear models for optimal control of nonlinear systems
(Institute of Advanced Scientific Research, 2009-12)
The optimal feedback control of nonlinear process is attacked in this paper. The solution of this problem is numerically computed using a Continuous Piecewise Linear (CPWL) approximation of the Ordinary Differential Equations ...
Dynamic ‘back‐off’ analysis: use of piecewise linear approximations
(John Wiley & Sons Ltd, 2003-04-10)
The operating point of a process is usually computed by optimizing an objective function, e.g. the profit, subject to some plant characteristics. Typically, the resulting point lies on the boundary of the operating region. ...
Partial Differential Equations for Missing Boundary Conditions in the Linear-Quadratic Optimal Control Problem
(Planta Piloto de Ingeniería Química, 2009-12)
New equations involving the unknown final states and initial costates corresponding to families of LQR problems are found, and their solutions are computed and validated. Having the initial values of the costates, the ...
Accelerated particle swarm optimization with explicit consideration of model constraints
Population based metaheuristic can benefit from explicit parallelization in order to address complex numerical optimization problems. Typical realistic problems usually involve non-linear functions and many constraints, ...
Non-Linear Transaction Costs Inclusion in Mean-Variance OptimizationInclusão de Custos de Transação Não-Lineares na Otimização Média-Variância
(Lociedade Brasileira de Finanças, 2005)
An inverse problem resolution via piecewise linear underestimationResolución de un problema inverso vía subestimación lineal a trozos

Surrogate-model based MILP for the optimal design of ethylene production from shale gas
(Pergamon-Elsevier Science Ltd, 2020-10-04)
We propose a novel algorithm for the optimal design of entire plants by refining piecewise linear surrogate models within an iterative framework. We apply this strategy to a superstructure for ethane-based ethylene production, ...
Optimal dual fusion frames for probabilistic erasures
(Int Linear Algebra Soc, 2017-06)
For any fixed fusion frame, its optimal dual fusion frames for reconstruction is studied in case of erasures of subspaces. It is considered that a probability distribution of erasure of subspaces is given and that a blind ...
