Improved cascade control structure for enhanced performance [PDF]
Journal of Process Control, 2007 In conventional single feedback control, the corrective action for disturbances does not begin until the controlled variable deviates from the set point. In this case, a cascade control strategy can be used to improve the performance of a control system particularly in the presence of disturbances.

An Alternative Control Structure for Grid-Following Converters of Inverter-Based Resources
IEEE Open Access Journal of Power and Energy, 2023 In this paper, an alternative control structure of grid-following control is proposed and applied in inverter-based resources (IBRs). An IBR’s grid-following control normally employs Power/Voltage (P/V) control strategy to control the output real ...

Optimization of lift gas allocation in a gas lifted oil field as non-linear optimization problem [PDF]
Modeling, Identification and Control, 2012 Proper allocation and distribution of lift gas is necessary for maximizing total oil production from a field with gas lifted oil wells. When the supply of the lift gas is limited, the total available gas should be optimally distributed among the oil ...

Structured computation of optimal controls for constrained cascade systems [PDF]
International Journal of Control, 2017 ABSTRACTConstrained finite-horizon linear-quadratic optimal control problems are studied within the context of discrete-time dynamics that arise from the series interconnection of subsystems. A structured algorithm is devised for computing the Newton-like steps of primal-dual interior-point methods for solving a particular re-formulation of the problem

Separating Mixture Glycols in DWC with Flow Rate-Composition Cascade Control Structure
Journal of Chemistry, 2022 Dividing wall column (DWC) is an advanced technology which could decrease energy consumption. As the vertical wall inserted in DWC increases the degree of freedom of systems, the control becomes more difficult than the conventional columns. In this study,
