Feedforward controller design by eigenvalue assignment.
The Journal of the Acoustical Society of America, 1991Active feedforward control algorithms have proved to be successful in the attenuation of stationary disturbances such as single, multiple frequencies, and random inputs. In feedforward control, the mean square value of a measurable response quantity induced by the disturbance input is minimized by coherent ‘‘secondary’’ control inputs.

For doubly fed induction generator (DFIG) based wind turbines, when severe grid faults occur, it is necessary to inject transient and negative-sequence components into the rotor current reference to achieve controllable low-voltage ride through (LVRT ...

Feedforward Compensation for PID Control Loops
2012This chapter presents methodologies for the design of feedforward control actions to be employed together with feedback PID controllers. Both set-point following and load disturbance rejection tasks will be considered. Regarding the set-point following task, after having presented the standard two-degree-of-freedom control scheme, the design of a ...

Performance indices for feedforward control
Journal of Process Control, 2015In this paper, a performance benchmark for the assessment of two feedforward control architectures for the load disturbance compensation problem is proposed. In particular, two indices are devised so that the advantage of using a feedforward compensator with respect to the use of a feedback controller only is quantified. Furthermore, these metrics will

Feedforward Control of Glass Mold Cooling
IFAC Proceedings Volumes, 1975Abstract This paper describes the feedforward control of air flow used to cool glass molds on a glass container forming machine. Feedforward action, based upon a heat transfer model and using a measurement of air temperature, changes the air flow so that the temperature of the glass is held constant. In the event the required air pressure exceeds fan

Orthogonal adaptation for multichannel feedforward control
The Journal of the Acoustical Society of America, 2006In active noise control, it is desired to generate destructive interference by model-independent control. This is possible for single-channel systems to which a recently proposed method, called orthogonal adaptation, is applicable. In this study, the new method is extended to multichannel systems.
