Reset controllers consist of two parts a linear compensator and a reset element. The linear compensator is designed, in the usual ways, to meet all closed-loop performance speci cations while relaxing the overshoot constraint. Then, the reset element is chosen to meet this remaining step-response speci cation. In this paper, we consider the case when such linear compensation results in a second...

Human visual sensitivity to a fairly broad class of dynamic stimuli can be modeled accurately using two temporal channels. Here, we analyze fMRI measurements of the temporal step response to spatially uniform stimuli to estimate these channels in human primary visual cortex (V1). In agreement with the psychophysical literature, the V1 fMRI temporal responses are modeled accurately as a mixture ...

In the paper a remote lab experiment RC oscillator used to support Web based learning, to support learning by doing, to learn control design and to minimize the gap between theory and practice is presented. The experiment was designed with a special care for visualisation of important control design parameters in Bode plot and Root-Locus diagram. The experiment is based on MATLAB, LABview and D...

AbsrractConventional fuzzy logic controller uses input membership functions that consist of identical triangular input membership functions (MF) for all the subsets that are not located at the two ends of the universal set (center width constant or CWC). Some researchers in the field of motor controllers have started using narrower base triangular membership functions for the input subsets that...

The direct synthesis (DS) tuning method is a model-based method for a feedback controller. The main principle of this method is to obtain the controller settings based on a predetermined desired closed loop response. The main advantage is that there is only one parameter to be adjusted, which is lambda (λ), the speed of the desired closed loop response. There are several guidelines available fo...

In this paper, we develop a dynamic lumped parameter model of a pneumatic membrane actuator to inform the design of a shape display that meets force, speed and spatial density specifications for refreshable braille. A system identification experiment is undertaken to determine relevant system parameters that remain fixed under variation of the lengths of the connecting tubes and cavity volumes....

A distortion analysis based on the large signal behavior of the basic switched-current memory cell is presented. In the first part, based on a closed form solution of the step response, distortion due to the settling error is addressed. In the second part, distortion caused by clockfeedthrough is analysed. The solutions are compared with simulated and/or measured results. Furthermore, harmonic ...

Ultrasonic motor’s model adapting to control application is the foundation of the motor’s high performance control. Ultrasonic motor’s frequency-speed control model gives a signification to improve speed control performance. This paper shows the design of stepping response experiments, and also explains the model identification of USM by the way of characteristic point method. Considering its t...

This paper presents a simple identification algorithm for linear models. The main motivation behind this algorithm is to familiarize students and engineers having limited mathematical knowledge with the principles of system identification without adding more mathematical burdens. This is achieved by using the principles of the step response coefficients and its explicit relation with the system...

In [BKT11] Baba, Kotyada and Teja introduced the FACTOR problem over non-abelian groups as base of an ElGamal-like cryptosystem. They conjectured that there is no better method than the naive one to solve the FACTOR problem in a general group. Shortly afterwards Stanek published an extension of the baby-step giant-step algorithm disproving this conjecture [Sta11]. Since baby-step giant-step met...
