This course on Control Systems aims to teach students the fundamental concepts and principles required for the GATE-2022 exam. By the end of the course, learners will be able to understand the basics of control systems, analyze open-loop and closed-loop systems, calculate transfer functions, and evaluate system stability. The course covers topics such as Laplace transforms, time response analysis, time domain parameters, steady-state error analysis, stability analysis using Routh-Hurwitz criteria, root locus diagrams, Bode plots, polar plots, Nyquist plots, and compensator design. The teaching method includes lectures, question discussions, and revision sessions. This course is intended for engineering students preparing for the GATE-2022 exam or anyone interested in gaining a comprehensive understanding of control systems.
