This paper examines methods to incorporate feedforward loops of known external inputs (output reference) into a multi-input feedback control structure achieve certain robust performance its output. Undoubtedly, can reduce the need for and therefore amplification sensor noise at actuators, as occurs in single-input control. Beyond that, since there are several available inputs, convenient distri...

Research over the past decade has demonstrated substantial increases in noise reduction performance for circumaural hearing protectors through feedforward active noise reduction (ANR) based on least mean square (LMS) methods. However, commercialization of feedforward ANR hearing protection devices has yet to occur. This paper explores issues related to robust realization of feedforward ANR for ...

As a new type of smart material, magnetic shape memory alloy has the advantages of a fast response frequency and outstanding strain capability in the field of microdrive and microposition actuators. The hysteresis nonlinearity in magnetic shape memory alloy actuators, however, limits system performance and further application. Here we propose a feedforward-feedback hybrid control method to impr...

This paper considers the design of feedforward controllers when model uncertainty is present. The main contribution is an alternative approach to the generation of the feedorward control action on the basis of the Internal Model Control formulation. This new structure allows for completely independent tuning of the feedback and feedforward controllers and provides an explicit expression for the...

Matching the brain’s flexibility and ability to quickly incorporate new information remains difficult using recognition algorithms. In addition, recognition scenarios in which humans require more time to recognize do not inherently require more time in recognition algorithms. This work proposes a recognition algorithm that uses dynamics in an opposite way from traditional recognition algorithms...

Purpose: Despite the widespread use of cryotherapy in sports fields there is a lack of certain evidence of its impact of it on muscle activation especially following fatigue-induced exercise. This study aimed to assess the impact of cryotherapy alone and after plyometric exercises on knee muscle activation during the drop jump task. Method: 35 active female subjects (mean age of 22.74±2.10, m...

We used in vivo intracellular recording techniques in order to provide evidence about the source of postsynaptic inhibition in the rat entorhinal cortex and subicular complex. Several different structures in the basal forebrain and hippocampus were electrically stimulated in order to activate inhibition by different pathways. This allowed a test of 2 different neuronal circuit models: feedback ...

Human early visual cortex was traditionally thought to process simple visual features such as orientation, contrast, and spatial frequency via feedforward input from the lateral geniculate nucleus (e.g., [1]). However, the role of nonretinal influence on early visual cortex is so far insufficiently investigated despite much evidence that feedback connections greatly outnumber feedforward connec...

We introduce a new structure for memory neural networks, called feedforward sequential memory networks (FSMN), which can learn long-term dependency without using recurrent feedback. The proposed FSMN is a standard feedforward neural networks equipped with learnable sequential memory blocks in the hidden layers. In this work, we have applied FSMN to several language modeling (LM) tasks. Experime...
