Defence, Marine and Aerospace Industries

ISC has been engaged on many marine defence related projects, both for surface ships and submarine, as well as working in control for avionics systems and land vehicles. Our latest developments are looking at control for Unmanned Vehicles.

We are usually engaged to provide technical support for early stage feasibility studies for large defence companies like BAE Systems, Rolls-Royce or QinetiQ. However, we do from time-to-time undertake troubleshooting problems for in-service or near-service control systems that are proving problematic.

We have skilled permanent UK National staff to undertake this work.

Example Projects
  • Combat Aircraft CD-ROM control - Improved head positioning control needed to counteract disturbances due to high accelerations. A Quantitative Feedback Theory (QFT) approach was proposed.
  • Nonlinear Compensation for Sensors - A bespoke algorithm was developed and analysed for the online compensation of sensor nonlinearities. As well as accuracy and computational burden, data diversity issues were paramount in this safety critical application.
  • Ship Roll Stabilisation Optimisation and Control - Gain scheduled controllers were optimised using models of vessel and wave dynamics. The solution was then tested on a nonlinear model of the vessel, and ISCs solution out-performed more advanced methods developed by academic groups.
  • Heave Compensation on Survey Vessel - A model of ship motion and heave compensation control were developed. The new algorithms were implemented on the ships PLC and tested at sea. (Download project presentation)
