Located currently at K26 lab.

Troubles:

  • the system is provided with the so-called turnkey solution, which means that besides the model itself, an amplifier and also the software was delivered.

Student projects finished with the system:

MATLAB® Controll using Real-Time Windows Target® and Humusoft Control Board

Individual Project
Krištof Pučejdl

Motivation:

  • Dedicated control software provided by ECP is very outdated. It requires old 32&nbspbit processor architecture and the user interface does not match today's standards.
  • Most of the control models being used in education are controlled via MATLAB® using universal Humusoft control board. Using the same board to control different models is way more flexible and allows switching the controll PC's without need of hardware changes.

Goals:

  • Find the correct setup of Humusoft board according to pin-out specification provided by ECP.
  • Set up and run the RTWT® communication in MATLAB®
  • Describe the input values to actuators and output values from sensors.
  • Experiment with regulators and feedback control.
