A suboptimal filter to be used for the nonlinear estimation problem in systems with piecewise linear models in both the system and observation equations is presented. The approximations used are based on utilizing the switched-Markov model for the system as well as on modifying the resulting filter with the physical constraints of the states of the model. Not all facets of the filter are in final form, and work remains in the area of the exact formulation of the consistency update, as well as filter aggregation. Nonetheless, preliminary results show that the filter may work well in a broad class of nonlinear filtering problems.
