Konetekniikka - Mechanical Engineering

The course gives an introduction to control in the context of mechatronic machines. As such, it gives a solid foundation of system dynamics and feedback control with a focus on common linear control and analysis methods. Both frequency and time domain methods for system analysis and control design are treated. Moreover, common kinds of industrial servo control systems are introduced, with a focus on electric and hydraulic actuation. Throughout the course, it is discussed how model knowledge is employed for control design and system analysis. Control design, analysis, and simulation are conducted mostly in Matlab / Simulink in this course. The course also contains substantial practical realizations and implementations of controllers, which is mostly done with small mechatronic hardware kits and compatible software. The course's theoretical content includes: - Introduction to control and its relation to mechatronics - System dynamics, in particular of linear systems in time and frequency domain - Feedback control with a focus on linear methods - Actuation in mechatronic machines - An intensive course on “Advanced Kinematics and Control of Wheeled Mobile Robots” in the autumn intensive week preceding the main part of the course (only for students who choose the implementation in Lahti).

The student obtains a job from a company aboard, works as a paid employee, requests a certificate of employment and applies for the approval of the work as an experience for the Master's degree. Full-time employment relationships of at least four weeks can be approved as experience. The job should be from the field of student’s specialization studies in mechanical engineering. The completion of the Master's thesis is not accepted as an experience. An employment relationship can be approved as an experience providing that it has not been accepted or included to any other course modules or in any other previous degree. An employment relationship that took place before M.Sc. level studies cannot be approved as an experience. The experience should support student's specialization studies in mechanical engineering.
