| We have recently proposed a general approach to engineering protective wrappers as a means of detecting errors or unwanted behaviour in systems employing an OTS (Off-The-Shelf) item, and launching appropriate recovery actions. This paper presents results of a case study in protective wrapper development, using a Simulink model of a steam boiler system together with an OTS PID (Proportional, Integral and Derivative) controller. The protective wrappers are developed for the model of the system in such a way that they allow detection and tolerance of typical errors caused by unavailability of signals, violations of constraints, and oscillations. |
