ISC has been engaged on many 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.
ISC were engaged to investigate a specific control loop on HMS Astute, reviewing current performance and making recommendations for improvements. A simple, but sufficient math model was built to demonstrate the proposed changes ahead of commissioning.
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.
Improved head positioning control needed to counteract disturbances due to high accelerations. A Quantitative Feedback Theory (QFT) approach was proposed.
