Feedback-feedforward control of a sewer
2001 European Control Conference (ECC), 2001This paper deals with the design of a feedback-feedforward controller for a sewer. The objective is to reduce the concentration of macromolecules (typically proteins, lipids and polysaccharides) entering the wastewater plant via the addition of a consortium of enzymes and bacteria in the sewer connecting houses to the plant.

Proceedings of 1994 American Control Conference - ACC '94, 2005
Some new results in learning feedforward control are presented in this paper. The proposed procedures are applicable to processes with or without feedback control. Under the ideal situation, this discrete-time learning control (LC) scheme can perfect the task with one repeat. Convergence analyses are also included for noisy and imprecise learning.

Application to Feedforward Control
2009To meet the continual quest for higher tracking accuracy in engineering practice, feedforward controllers have become an essential complement to feedback control. The ideal feedforward controller inverts the (closed-loop) system and as it yields perfect tracking for any reference input, specialized feedforward design for periodic inputs seems ...

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

Multirate feedforward control of robot manipulators
2007 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2007This paper introduces a novel multirate feedforward control method for robot manipulators with elastic joints. Perfect tracking control methodology using multirate feedforward control was proposed by H. Fujimoto, et. al. Furthermore, A. Shimada, et. al.

Analysis of Memory as a Feedforward Control Mechanism
Journal of Motor Behavior, 1969The properties of memory as a feedforward control mechanism of perception and motion have been investigated by requiring Ss to project in active space-time an observed stimulus wave pattern. Memory error was measured under conditions in which the visual feedback of the memory response was delayed and interrupted (sampled) at five time magnitudes (0.0 ...

Feedforward/Feedback Controls in a Noisy Environment
IEEE Transactions on Systems, Man, and Cybernetics, 1986A nonlinear controller useful in situations is presented, in which variable external disturbances are measured with a high-quality sensor. In many applications, feedforward and feedback control are employed in a complementary manner to produce satisfactory response.

On Parallel Feedforward and Simplified Adaptive Control
IFAC Proceedings Volumes, 1987Abstract Simple adaptive control systems were recently shown to be globally stable and to maintain robustness with disturbances if the controlled system is “almost strictly positive real” namely, if there exists a constant output feedback (unknown and not needed for implementation) such that the resulting closed loop transfer function is strictly ...
