Stationary Helicopter
Thinking about what a CDE (culminating design experience) should be, we devised a project that combines the microcontroller programming principles learned in ECE 476: Microcontroller Design with the control theory concepts learned in ECE 472: Feedback Control Systems to create an academically viable stationary helicopter. The device consists of a lever with a DC-motor-driven propeller attached to one end. The angle of the lever is determined by an accelerometer-based PID (proportional-derivative-integral) feedback-controller. The accelerometer signal is fed into a Mega32 MCU (microcontroller unit) that the user interacts with, using push-buttons to set the desired angle and to adjust control parameters.
