Key questions and answers

Question 1: What is the difference between the USB version and embedded version of QUBE Server 2 core? What teaching scenarios are suitable for each?

answer:

The USB version uses USB 2.0 to connect to a computer and is compatible with MATLAB/Simulink/LabVIEW, making it suitable for teaching control theory, system modeling, and automatic control experiments.

The embedded version uses SPI interface and can be directly connected to Arduino and Raspberry Pi without the need for upper computer software. It is suitable for microcontroller development, electromechanical practice, and graduation design.

Question 2: What typical control teaching experiments can this device carry out? What are the core control algorithms?

Answer: Two types of core experiments can be conducted:

Inertial disk experiment: system modeling, filtering, PD control, stability analysis.

Inverted pendulum experiment: state space modeling, LQR state feedback control, balance and swing up control.

Question 3: What is the biggest advantage of QUBE Server 2 in teaching use? Why can we quickly set up a laboratory?

Answer: The biggest advantage is integrated hardware, complete course materials, and multi platform compatibility. It comes with ABET certification laboratory lecture notes, textbook mapping, ready-made models and controllers, which can save teachers months of development time and start classes right out of the box.
