Cascade Control Proposal for the Attitude of a CubeSat 1U Satellite.

Research project where was developed a new Guidance, Navigation and Control (GNC) law for Attitude Determination and Control Systems (ADCS) of CubeSat satellites.

Year: 2016.

Simulations.

Reaction Wheel Model in Simulink.

An early version of the RW model. Used the motor properties obtained from a previous project in which a DCPM motor was characterized.

Cascade Control in Simulink.

A multi-loop (two control loops) for the attitude control of a 1U CubeSat. The inner loop is about the dynamics of the characterized RW. The external loop is about the satellite dynamics.

Attitude Control in Simulink.

Cascade control response with enviromental disturbes included.

In figure:

• Magenta: reaction wheel's angular speed (\omega_r(t)).
• Red: satellite attitude in (roll (x(t))).
• Cyan: setpoint, from 0 to 1° in 10 seconds.
