State-Of-The-Art Submarine Autopilot and Hover Systems Design and Development
We specialise in the development of safety-critical steering diving control systems and state-of-the-art autopilot and hover solutions that are easy to integrate while delivering enhanced control and performance.
Our expertise extends from the design of the control algorithms all the way through to the implementation of the safety-critical software code and on-board control systems. Similarly, our technology benefits legacy platforms as well as existing state-of-the-art submarine control, and incorporates a future product concept that reduces manning and simplifies boat control.
Developing an automatic submarine platform control system to meet today’s operational requirements is a highly-complex undertaking, with large and potentially expensive technical risks being carried through the development project until successful sea trials are conducted. Stirling’s advanced autopilots deliver optimised boat performance coupled with a robust control system. The experience we have gained from our military aerospace background has been applied to the submarine environment to increase performance, reliability and safety.
Stirling autopilots enable an extended operational envelope and increased safety. They are also designed to minimise operator workload and training requirements, and have the facility to be tuned at sea during sea-trials.
We also develop market-leading hover and variable ballast control system algorithms for submarines. These systems provide automatic control of the trim and compensation plant to provide depth control at low speeds, while our low speed control offers depth control in challenging sea states; depth change capability; steady state pitch angle control; disturbance rejection due to density changes; and stores release. The hover control system, in parallel with hydroplane control, can provide disturbance rejection due to effects such as stores release (missile compensation), density changes and compressibility.
Submarine Control System Design
Stirling autopilots are currently installed on six different classes of submarine in a variety of different configurations, and are in service with many different navies across the globe.
Astute Class Platform Management System Central Computer Software
Stirling has been involved with the Royal Navy Astute submarine programme since 1996, initially providing the algorithm designs for both the depth and course autopilot and the hover system for Boats 1 to 3. For Boat 4, in addition to the algorithm design, Stirling are supplying the PMS (Platform Management System) central computer software.
