Synchronization of N-Non-Linear Slave Systems with Master System Using Non-Adaptive and Adaptive Coupled Observers

Synchronization of N-slave chaotic systems with a master system is a challenging task, particularly in recent times. In this paper, a novel methodology is proposed for synchronizing the N number of slave systems with a master system. The proposed methodology is based on coupled adaptive synchronous observers. The difference between the corresponding states of master and slave systems is converged to the origin by means of a novel feedback control scheme to achieve synchronization between the master and slave systems. The efficacy of the proposed methodology is verified through a simulation of FitzHugh–Nagumo non-linear systems in MATLAB. The simulation results validate and prove claims, and these systems are successfully synchronized by CCS and CCAS observer-based control

Comparative study of CFSI,Trans-CFSI and SL-QSBI

This paper presents the comparative analysis of the three types of inverters which are Current-Fed Switched Inverter (CFSI), Trans- Current-Fed Switched Inverter (Trans-CFSI), and improved Switched Inductor-Quasi Switched Boosted Inverter (SL-QSBI). Also, a simple boost Pulse-Width- Modulation (PWM) Scheme is applied to CFSI, Trans- CFSI, and improved SL-QSBI. Each inverter category is analyzed separately for evaluating the effect of variation in duty ratio on the modulation index and boost factor. The comparisons of these inverters are rendered to quantify the voltage boost ability, voltage stress on the switching device and the voltage gain ability. Moreover, a simple boost control scheme is also modified to attain high modulation index. The efficacy of the proposed results is verified using the Saber software simulations
