Abstract

This paper describes safety monitoring features for an inductive rotary position sensor having analog, position dependent sine and cosine outputs. An algorithm is presented that estimates a position error by analyzing the variation of the magnitude or signal strength derived from the sine and cosine output signals. The presented Simulink Model aims at efficiently validating the performance of the safety mechanism (SM) under plausible failure modes during the operation of the product. Random failures could occur in each element of the positioning system. By analyzing simulation results of the injected faults with the Simulink model, it is possible to predict the sufficiency of the magnitude ripple check algorithm. The Simulink model implemented proves to properly verify the implementation of the SM.
