Learning Outcomes
After the course the student knows the potential and limitations of decision & control both within and beyond actual control engineering; knows typical control structures as well as connections and the roles nature of the control system components; can derive simple dynamical models, simplify models and perform model conversations; masters typical system terms and concepts including performance specifications; is able to describe and analyze control systems and other dynamical systems; understands and can analyze and even limitedly design stability, damping, accuracy and speed of systems with standard methods; is able to analyze potential stability and performance risks due to uncertainty and guard against them; can exploit use Matlab, Simulink, Control System Toolbox and Symbolic Toolbox or another similar enough software in the tasks mentioned; is able to communicate on these things with students and engineers educated elsewhere.
