Title: A guest Lecture on Nonlinear Dynamical system

Resource Persons:   Dr. Piyush Pratap Singh (National Institute of Technology Meghalaya)

                                                             Brief description/ Remarks:

The Department of Electrical and Electronic Engineering recently organized an online guest lecture, focusing on a rather intricate topic: “Nonlinear Dynamical Systems.” This lecture was specifically tailored for B.Tech and M.Tech students enrolled in the Electrical and Electronic Engineering programs. The event was scheduled on August 26th, 2023, from 11:00 AM to 01:00 PM. The virtual setting for this knowledge-sharing session was the Power System Laboratory.

The primary goal of this lecture was to introduce students to the concept of nonlinear dynamical systems and how they can apply it in the field of electrical and electronics engineering. Dr. Piyush Pratap Singh, an Assistant Professor from the Department of Electrical Engineering at the National Institute of Technology, Meghalaya, was the guest speaker. He aimed to enlighten the students on several key aspects:

1. Linear vs. Nonlinear Systems: The lecture kick-started by explaining the difference between linear and nonlinear systems. This foundational knowledge is essential to understand the complexities that follow.
2. Dynamical and Complex Systems: Dr. Singh then delved into the world of dynamical and complex systems, such as chaos, bifurcation, PDB (Period Doubling Bifurcation) which are often encountered in real-world scenarios. Understanding these concepts is crucial in engineering.
3. Analysing Nonlinear Behaviour: He also discussed the tools and methods used to analyse nonlinear behaviour such as time series, phase portrait, bifurcation diagram, Lyapunov exponents etc. These techniques empower engineers to make sense of intricate systems.
4. Mathematical Modelling of Nonlinear Dynamical Systems: Dr. Singh provided insights into mathematical modelling, focusing on mathematical model of Lorenz System, Rössler System, Pendulum and Duffing Oscillator. This bridged the gap between theory and practical engineering.
5. Impact on Power Systems: The lecture concluded by examining how nonlinear behaviours can significantly affect power systems. This part highlighted the real-world consequences and challenges posed by nonlinear elements in electrical systems.

In essence, this online guest lecture was a valuable educational experience for the students. It equipped them with a deeper understanding of nonlinear dynamical systems, which are a crucial aspect of electrical and electronics engineering. Dr. Piyush Pratap Singh’s expertise and insights undoubtedly left a lasting impression on the students, fuelling their curiosity to explore this fascinating field further.
