An active diagnostic algorithm for a gyroscopic sensors unit

An extended diagnostic algorithm for a gyroscopic sensors unit (GSU) is presented. Its effectiveness has been proven with a computer program that emulates faults in the system. The algorithm has the ability to perform a diagnosis of the GSU and constantly monitors its state by means of several mathematical models. Once the algorithm detects the presence of a fault, it can determine which one is the faulty sensor and define the kind of fault that has occurred. This diagnosis can lead us to perform the possible corrective actions and recover the optimal performance in the GSU. The algorithm's effectiveness and results are presented in this work.
