In this paper, the min-time optimal control problem is mainly investigated in the linear time invariant (LTI) continuous-time control system with a constrained input. A high order dynamical LTI system is firstly considered for this purpose. Then the Pontryagin principle and some necessary optimality conditions have been simultaneously used to solve the optimal control problem. These optimality ...
In this report. wave propagation inside a perfectly conducting room with two homogeneous dielectric walls has been studied. The thicknesses and losses of the dielectric walls are arbitrary. therefore it is possible to model wave phenomena inside various indoor environments. Green's function technique is used to calculate the electric fields excited by point sources and half wave dipole transmit...
In this paper we studied the performance of an STOLAS project based node switching an FSK/IM modulated signal. A simulation model for 10Gbit/s IM modulated payload FSK labelled at 155Mbit/s, of an optical label switching node, has been developed. The performance of a single node, the effect of the crosstalk between channels and the impact of the extinction ratio value of the IM signal on the ov...
Due to growing complexity and costs of hardware systems, computer architects traditionally rely on software simulation to evaluate new designs. Although software simulation excels in convenience and flexibility, it suffers from prohibitively long turnaround time. Researchers are constantly searching for methods to accelerate software simulations. SMARTS is a framework that uses rigorous statist...
<span>The work has presented duobinary modulation and predistortion techniques for the radio over fiber system enhancement achieving security level. Duobinary technique more compact modulated spectral linewidth with standard non return to zero code. Different NRZ/RZ rectangle shape employed that are namely exponential (ERS), Gaussian (GRS) different transmission bit rates. Switching bias ...
A switched system is a hybrid dynamical system consisting of a family of continuous-time subsystems and a rule that orchestrates the switching between them. Many systems encountered in practice exhibit switching between several subsystems that is dependant on various environmental factorss1]. In this lecture we are going to go over two robotic applications of switched sytems. Namely, Underactua...
We study controllability of switched differential algebraic equations. We are able to establish a controllability characterization where we assume that the switching signal is known. The characterization takes into account possible jumps induced by the switches. It turns out that controllability not only depends on the actual switching sequence but also on the duration between the switching times.
We theoretically investigate the switching properties of nonlinear electron-wave directional couplers by applying the coupled mode theory. Analytical results for the probability of finding the electron wave in each waveguide, for arbitrary initial occupation of each waveguide, are presented. Our findings reveal that several technologically important cases can be achieved, such as significant or...
