I think the problem is in Q. Q are charging K with their values. I achieve good results when Q is preloaded with powers of delta_t. See any article about wiener model. It has a good Q matrix. A00 has to be multiple of delta_t power of 5 A11 delta_t power of 3 A22 delta_t power of 1 A01 multiple of delta_t power of 4 And so on Look at https://www.google....


A resistance isn’t a particularly dynamic state, should be an unknown constant, but you might have a bin of resistors where they might vary. Taking one “randomly” out the bin makes it a random variable. The bin of resistors will have a mean value, so perhaps that mean constitutes a state variable. Perhaps someone starts putting resistors in the bin from a ...
