ME401: Dynamic Systems & Controls

Unit 3: Control Systems Design   Every dynamic system has a control (corrective) action for a desired response.  For instance, a car’s cruise control can help you drive at a given velocity.  A dynamic system cannot be designed completely without incorporating some form of controller.  Feedback Controllers (i.e. proportional (P), derivative (D), integral (I), or combinations thereof, like PI, PD, or PID) are commonly used in the industry.  These controllers are commonly designed in time-domain.  SCILAB should be used wherever appropriate to prevent errors in hand calculations and to validate calculations elsewhere.
