1. The problem statement, all variables and given/known data Identify 10 feedback systems that you encounter in your everyday environment. For each system, identify the sensing mechanism, actuation mechanism and control computation. Describe the uncertainty with respect to which the feedback system provides robustness and/or the dynamics that are changed through the use of feedback. 2. Relevant equations NA 3. The attempt at a solution 1) Toilet water tank Sensing mechanism - Float Actuation mechanism - When the water level goes down, the float goes down which it opens the fill valve. As the water fills the tank, the float goes up & at a certain point, closes the fill valve. Control Computation - No idea Uncertainty/robustness etc - Not sure 2) Cruise Control Sensing mechanism - whatever measures the speed in a car. Actuation - Solenoid driven throttle and brake? Control Compution - ? Uncertainty/Robustness - not sure 3) Elevator Sensing mechanism - Sensors at each floor level. Actuation - Sensors stop the elevator? Control Compution -? Uncertainty/Robustness - not sure 4) Climate Control Sensing mechanism - thermometer Actuation - ON/OFF of compressor. Control Compution - ? Uncertainty/Robustness - not sure ???
