Completion parts must belong to the same implementation

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.

Implementation Description Methods of instruction Implementation
ASE-1257 2014-01 ASE-1257 is a course with 24 lecture hours, 24 exercise hours, 1 LAB hour, 8 PC hours plus exams. Sessions with "ASE-1256:" are not included in ASE-1257 but may be taken bý students who want to replace ASE-1257 of 4cr to ASE-1256 of 6cr due to a request of their home uni. Course administrator: Associate Professor Terho Jussila.        
ASE-1257 2014-02 Spring 2015 implementation without lecture and pen-and-paper exercise sessions but with the compulsory LAB, PC and exam sessions. A wider course ASE-1256 of 6 cp is available on a special request by the student.
