This course introduces students to modelling and control of engineering systems. It presents tools that are fundamental for the analysis and design of such systems. The tools presented in the course use energy as a key element to develop modelling skills that can transcend physical domains and engineering specialisations. In addition, the course provides students with an understanding of the principle of feedback along with an introduction to classical control design techniques. Topics include fundamental limitations, stability of closed loop systems, control design for time domain and frequency domain specifications.
