Feedforward model predictive control

Annual Reviews in Control, 2011
Abstract This paper examines the role played by feedforward in model predictive control (MPC). We contrast feedforward with preview action. The latter is standard in model predictive control, whereas feedforward has been rarely, if ever, used in contemporary formulations of MPC.

Industrial feedforward control technology: a review

Journal of Intelligent Manufacturing, 2018
In the control field, most of the research papers focus on feedback control, but few of them have discussed about feedforward control. Therefore, a review of the most commonly used feedforward control algorithms in industrial processes is necessary to be carried out.

Inferential feedforward control of a distillation column [PDF]

Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001
An inferential feedforward control strategy is developed and applied to a simulated distillation column. In this control strategy, the effects of disturbances on the primary process variables (top and bottom compositions) are inferred from uncontrolled secondary process variables (tray temperatures) which can be easily measured. The proposed strategies

Predictive feedforward control

2016 12th IEEE International Conference on Control and Automation (ICCA), 2016
Measurable but controllable disturbances are common in industry, which drive systems away from their references and take time for feedback control to reject them, especially when the systems present input-output delays due to mechanical properties. In this paper, a novel feedforward control based on disturbance prediction is proposed.

Approximate feedforward control

2015 10th Asian Control Conference (ASCC), 2015
Disturbances are inevitable in most control systems. They drive the systems away from their set points. It takes time for feedback control to reject them. The feedforward control offers great potentials for regulation performance if the disturbances are measurable.

Feedforward mapping for engine control [PDF]

IECON 2016 - 42nd Annual Conference of the IEEE Industrial Electronics Society, 2016
Feedforward control is widely used in electronic control units of internal combustion engines besides feedback controls. However, almost all feedforward control values are used in table form, also called maps, having engine speed and engine torque in their axes. Table approach limits all interactions in two input dimensions.

Feedforward control of flexible manipulators

Proceedings of the IEEE 1991 National Aerospace and Electronics Conference NAECON 1991, 2002
A method to control the tip position of single-link flexible manipulators is presented. The method is based on the dynamic model inversion technique. The feedforward controller obtained as a result of this inversion drives the arm along a commanded trajectory without any oscillation of the tip.

Feedforward control in the presence of uncertainty

Industrial & Engineering Chemistry Research, 1988
In this paper, a new systematic approach to the design of feedforward-feedback (FF-FB) control systems is proposed, applicable in cases where bounds on plant and disturbance uncertainties are known. The robust performance of this control scheme is compared with that of two alternative feedback designs, on the basis of a test case in which the ...

Fuzzy feedforward and composite control

Transactions of the Institute of Measurement and Control, 1986
The concept of fuzzy feedforward and composite control of complex, ill-defined, non-deterministic processes is offered. Fuzzy relational model of process suitable for feedforward control is developed and, using this model, the algorithms of the fuzzy feedforward and composite controls are derived.
