MC 301 Digital Feedback Control Systems

This is the second course in the Mechatronics feedback control sequence.  It includes a review of Analog Control Systems and introduces the concepts and tools of Discrete-Time Systems as used in real-world control systems. Clarity in important concepts (e.g. sampling, aliasing, quantization, stability, etc.) is provided through simulation of Feedback Control and Discrete-Time systems using MatLab.  Extensive use is made of the “CTM Control System Tutorials”* for example control systems and analysis.
