As before, the channel input is an i.i.d. sequence, and the noise is stationary and white with SNR,h,, =20 dB. We assume the number of feedforward taps is fixed at q = 10. Fig. 3 shows the optimal decision delay (defined as thlat which maximizes SNRDFE) versus the number of fee...

In previous work, we compared the raster tracking performance of two distinct combined feedforward/feedback control architectures while using model-inverse control [1], [2]. In this paper, we extend that previous work into the application of parallel and serial iterative learning control (ILC) architectures. These ILC architectures naturally relate to the two previously studied combined feedfor...

Nonminimum Phase Discrete Time Models Yuping Gu and Masayoshi Tomizuka Department of Mechanical Engineering University of California at Berkeley, Berkeley, CA 94720-1740 [email protected] [email protected] Abstract This paper is concerned with performance enhancement of tracking control systems by multi-rate control. The feedback controller is updated at the same rate as the sampling r...

In this paper, with a modest amount of modeling effort, a feedback–feedforward control structure is proposed for precision motion control of a permanent magnet linear motor (PMLM) for applications which are inherently repetitive in terms of the motion trajectories. First, a proportional integral derivative (PID) feedback controller is designed using a relay automatic tuning method. An iterative...

Identifying inter-area communication in terms of the hierarchical organization of functional brain areas is of considerable interest in human neuroimaging. Previous studies have suggested that the direction of magneto- and electroencephalography (MEG, EEG) source currents depend on the layer-specific input patterns into a cortical area. We examined the direction in MEG source currents in a visu...

In the visual cortex, feedback projections are conjectured to be crucial in figure-ground segregation. However, the precise function of feedback herein is unclear. Here we tested a hypothetical model of reentrant feedback. We used a previous developed 2-layered feedforward spiking network that is able to segregate figure from ground and included feedback connections. Our computer model data sho...
