In this paper, a modified double scroll chaotic attractor circuit, which is employed as a true random binary number generator (TRBNG), is presented for use as a key source in cryptographic applications. The double scroll attractor is modelled on Chua’s circuit for nonlinear operation leading to chaotic behaviour. Previous reported versions of this circuit(More)
An accurate mathematical model of a three phase brushless motor drive (BLMD) system, based on physical principles, is presented for simulation in performance prediction studies of proposed embedded drive systems. This model can also be deployed for parameter identification of the adjustable speed drive (ASD) dynamics in optimal PID controller design and in(More)
In this paper the topology of a novel double scroll chaotic attractor circuit used for true random binary sequence (TRBG) generation is detailed. The novel cascade design of a chaotic oscillator with a pseudorandom binary sequence generator (PRBSG), used for key stream whitening, is described for encryption applications. The advantages of the employed PRBSG(More)
In this paper a novel pulse sequence testing methodology is presented [22] as an alternative to Time Domain Reflectometry (TDR) for transmission line health condition monitoring, faultfinding and location. This scheme uses Pseudo Random Binary Sequence (PRBS) injection for transmission line testing and fault location with cross correlation (CCR) techniques(More)
A novel analytical technique is presented for the determination of the modulated pulse duration in sinusoidal asynchronous pulse width modulated (PWM) systems. A reasonable level of modulated aperture accuracy can be obtained with little computational effort using the proposed method. The method of evaluation of the pulse edge transitions is based on a(More)
