Purpose of the course: This course enables students to develop mathematical models from first principles to represent the behavior of various physical systems, including mechanical, electrical, and electromechanical systems. Students will learn to utilize basic engineering approximations to simplify these models and develop system responses to various types of inputs. The course covers analytical modeling techniques such as Laplace transforms and the state-space approach for analyzing dynamic systems.
In addition to modeling, students will use time-domain and frequency-domain analysis to evaluate system performance. Fundamental concepts of control engineering—including feedback control systems, system stability, and basic control design—are introduced to provide a foundation in modern control systems.
