“A leak in a pipe would be simulated with a corresponding drop in pressure,” explains Worthington. It also needed to model physical faults as events with secondary effects. To make the OBT realistic, the team needed to activate approximately 4000 inputs and outputs to PMS with many more internal signals to interconnect the 16 systems it emulated. To handle inevitable changes to system requirements, the engineers needed to be able to trace requirement changes, make design modifications, and communicate those changes with each other and with the customer. ChallengeīAE Systems Surface Ships engineers had to develop the OBT plant simulation before the systems it emulated were fully designed, and concurrently with the design of the PMS. “By modeling and simulating the ship’s systems in Simulink, we provided a safe learning environment for the crew and gave valuable feedback to the main Type 45 project team at an early stage,” says Peter Worthington, principal engineer at BAE Systems Surface Ships.
PLANT SIMULATION COMMUNITY OFFLINE
The OBT enables crew members to take their workstations offline to run training simulations it is the Royal Navy’s first on-ship trainer of this type.īAE Systems Surface Ships developed the OBT plant simulation using MathWorks tools and Model-Based Design. The trainer simulates, in real time, the Type 45’s sophisticated electric propulsion, generation, and auxiliary machinery, which can be simultaneously controlled by up to 16 crew members via the Platform Management System (PMS). Instructors aboard the Type 45 Anti-Air Warfare destroyer, the Royal Navy’s most advanced and largest warship of its type, will use an On-Board Trainer (OBT) to train crew to control, reconfigure, and recover the ship’s main systems in a variety of machinery fault and action damage scenarios. Crew members responsible for operating modern warships must train extensively to master the control of the vessels’ systems.
