A PD controller is designed and implemented to control the flywheel to trace a circle through several waypoints. Click on the image below to watch the video.

Make sure you line up the slots and then push and turn the connector clockwise to lock. Reverse the procedure to disconnect the cable. Click the image below to play the video.

Make sure to put the magnet right-side up and underneth the rim of the copper flywheel. Click the image below to play the video.

Use command “plot(simout)” in Matlab, where ‘simout’ is the data variable name of the block “To Workspace”. Check the data format of ‘simout’ to ensure the accuracy of a data plot.

A BNC “T” (or Tee) connector has a T shape design that splits a BNC male input port into two female output ports

To do numerical integration of a time signal in Matlab, you can use the ‘cumsum’ function. For example,

int_signal = cumsum(signal)*dt;

where ‘signal’ is a one dimensional arry containing signal values, and ‘dt’ is the sample period in seconds.

The name BNC (Bayonet Neill–Concelman) is originated from its bayonet mount locking mechanism (a cylindrical male side with one or more radial pins, and a female receptor with matching L-shaped slot(s) and with spring(s) to keep the two parts locked together) and its inventors, Paul Neill and Carl Concelman.

The Arduino UNO is an open-source microcontroller boardbased on the Microchip ATmega328P microcontroller.  The board has 14 Digital pins, 6 Analog pins, and programmable with the Arduino IDE (Integrated Development Environment) via a type B USB cable. It can be powered by the USB cable or by an external power source with a supply voltage between 7 and 20 volts.
