Next Generation Subcutaneous Injector Device



Sašo Jezernik


Altran AG is developing the next generation electronic, software controlled injector device with the purpose of providing automatic subcutaneous injection of liquids. The development is supported by a HIL, custom drive test-bed including a precision force generator enabling to develop and test the injection procedure. Two types of controllers are currently being used: PID cascaded position / velocity controller and an advanced controller with load observer and built in load compensator. The test-bed is documented with a user manual, installation and start-up instructions as well as subsystem information.

Project tasks

The objective of this semester work is to:

  • 1. Understand and bring the existing system up and running
  • 2. Define and implement 3 test cases with 3 load-force profiles
  • 3. Test, compare and evaluate the performance of the 2 currently used controllers
  • 4. Optimise controllers with respect to performance
