This paper looks at the implementation of a Sliding Model Observer (SMO) based reconfiguration algorithm to deal with sensor faults within the context of navigation controllers for Autonomous Underwater Vehicles (AUV). In this paper the reconfigurability aspects are considered for the main heading controller. Simulation responses are used to illustrate that the Sliding Mode Controller is able to give state information to the controller when there is a fault in the AUV's sesnor package. Comparisons are made between the Sliding Mode Controller with and without reconfigurability for a number of different sensor failures, e.g. bias errors in or the complete loss of the heading data, and the robustness of the Sliding Mode Observer is investigated through the introduction of disturbances into the system.
