Grid-Connected Inverter Grid Voltage Feedforward Control Strategy Based on Multi-Objective Constraint in Weak Grid

Energies
In weak grid, feedforward of grid voltage control is widely used to effectively suppress grid-side current distortion of inverters caused by harmonics in point of common coupling (PCC) voltage. However, due to its introduction of a positive feedback loop

FEEDFORWARD CONTROL OF MULTISTAGE PROCESS

JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 1971
The feedforward control of co-current stage processes has been investigated. Forming inner feedforward control loops inside the stage process is expected to improve the process dynamics. To get suitable control response to load change, parameter optimization is discussed.

A Multi-Resonant based reference feedforward adaptive voltage control for Grid-Forming inverter in island mode to compensate system uncertain and harmonic distortions

International Journal of Electrical Power & Energy Systems
This paper investigates a novel adaptive voltage control over a three-phase grid-forming (GFM) inverter. The proposed voltage controller includes two function parts: power control input and signal control input. The former improves dynamic performance by

Input filter compensation for switching regulators [PDF]

The problems caused by the interaction between the input filter, output filter, and the control loop are discussed. The input filter design is made more complicated because of the need to avoid performance degradation and also stay within the weight and ...

Feedback and feedforward control in apraxia of speech: Noise masking effects on fricative production [PDF]

, 2014
The present study tested two hypotheses about apraxia of speech (AOS), framed in the DIVA model (Guenther, Ghosh, & Tourville, 2006). The DIVA model assumes that speech targets are regions in auditory space, and combines two mechanisms to reach those ...
