Accuracy is one of the most important factors in model-based design, but it is not an absolute measure. The precision you can achieve depends on a number of variables, such as the quality of the sensor data, the stability of the overall system and the way the model has been built.
One of the key advantages of model-based design is the ability to run a vast number of virtual scenarios. By simulating many different conditions, the control system can be made more stable and robust, and the optimisation can be refined to a very high level. This approach allows engineers to capture those extra percentage points of performance that are difficult to achieve with physical testing alone.
Because so many edge cases and fault scenarios can be simulated early, engineers are better prepared for integration. This reduces delays, avoids late rework, and gives higher confidence in how the system will behave once deployed.
It is not realistic to expect a model to perfectly replicate real-world behaviour in every case, but model based design allows us to get as close as possible before hardware testing begins. It provides a far broader view of how a system will behave, highlights edge cases that might cause problems, and ensures that when physical tests do take place, they are focused on validation rather than discovery.
This focus on early virtual accuracy shortens the overall programme timeline. It also improves the quality of hardware testing, since much of the uncertainty has already been removed through simulation.
Whether in motorsport, aerospace, energy or manufacturing, this focus on accuracy during the virtual development phase means better performance, fewer surprises and a smoother transition from design to operation.
