Feedforward controlis an open-loop scheme that compensates thesystem dynamicswithout needing information about the system states as the tracking error. For such reason, it requires precise knowledge about the dynamics of the system to be controlled. However, it is practically impossible to have accu...
Rh3, Rh5, and Rh6 are further restricted to specific PR subtypes by Sens, Pros, Ss (via Dve), and the Wts/Melt loop. We also show that Dve is expressed in yR7s at levels that are sufficient to repress Rh3 throughout most of the retina but low enough to allow for IroC-mediated ...

Despite the importance of inhibitory GABAergic parvalbumin-expressing (PV+) interneurons to PFC circuit function and decades of interest in N-methyl-D-aspartate receptors (NMDARs) in these neurons, examples of defined circuit functions that depend on PV+ interneuron NMDARs have been elusive. Indeed...
The feedback and feedforward controllers do not affect each other and can be designed independently based on the open-loop plant to achieve stability, disturbance rejection and command tracking, respectively. Numerical examples are given for illustration.doi:10.1080/00207178708934001...
Our work provides examples of the bidirectional interactions that happen between GC cells and the peritoneal mesothelial cells: GC cells promote mesothelial fibrosis, and the latter reciprocates by prompting migration of GC cells, thereby constructing a potentially self-amplifying positive feedback loop....

Examples Field-Weakening Control (with MTPA) of PMSM Implements the field-oriented control (FOC) technique to control the torque and speed of a three-phase permanent magnet synchronous motor (PMSM). The FOC algorithm requires rotor position feedback, which is obtained by a quadrature encoder sens...
(Vref), and an output. The compensation circuit204is coupled between the output of the error amplifier202and ground220. In at least some examples, the compensation circuit204includes one or more passive components (not shown), such as capacitors and/or resistors, which may filter or otherwise ...
A feedforward amplifier having a distortion detection loop and a distortion elimination loop is provided that achieves increased accuracy, improved response, and stable operation. A variable attenuator is placed in front of a detector in a loop output stage, and the amount of attenuation in the va...
