    An algorithmic approach for multiple fault diagnosis of linear discrete-time systems is proposed. Based on notions of an expected deviation vector and variation factors, it is shown that t faults in functional units of a dynamic system can be diagnosed with t+1 sample times. The method is considered efficient when the number of faults is unknown but small and when the sampling pe... View full abstract»

    Three alternative approaches for eliminating steering discontinuities are presented: changing the steering mechanism, changing the guide-point on the cart, or changing the curves on the path. The first approach requires a steering mechanism that allows the cart to move in any direction without changing its heading. The most common configurations in an automatically guided vehicle are the steered-w... View full abstract»
