2.737 Mechatronics (MIT) 2.737 Mechatronics (MIT)

Description

This course teaches the design of mechatronic systems which integrate mechanical, electrical, and control systems engineering. A computer hard disk drive is an example of a complex mechatronic system discussed in the class. Laboratories form the core of the course. They cover topics such as aliasing, quantization, electronic feedback, power amplifiers, digital logic, encoder interfacing, and motor control. The labs make extensive use of Simulink®, a MATLAB® toolbox which allows for graphical simulation and programming of real-time control systems. The new lab facilities feature dSPACE digital signal processors which are programmed through Simulink®. Each student builds circuits on a breadboard kit which is issued to them.
