Abstract :
For Part I, see ibid., pp. 2162-7 (2000). We present an algorithm for state estimation under partial observation with time using an extended TTM (timed transition models). In particular, given the reachability graph (RG) of the original underlying TTM, the observer computes the state uncertainty that arises due to immeasurable state transitions along the given trajectories of the RG of the system, after the occurrence of every measurable transition or tick. The algorithm is illustrated by an example of a single-cylinder hydraulic punching machine
