Accumulation-based concurrent fault detection for linear digital state variable systems

An algorithmic fault detection scheme for linear digital state variable systems is proposed. The proposed scheme eliminates the necessity of observing the internal states of the system for concurrent fault detection by utilizing an accumulation-based approach. Observation merely of the inputs and the outputs results in significantly reduced area overhead and no performance penalty. Experimental results verify that 100% concurrent fault detection is attainable for linear digital state variable systems.
