On the basis of deeply studying the Kalman filter algorithm, the engineering design method of multi-model Kalman filter is proposed. A large number of simulation studies are carried out for the second-order system and the ship model respectively. The results show that for the system with parameter mutation, the method can be used to estimate the state or identify the parameters, which has a good effect of tracking the mutation parameters. Simulation results show that this method has a broad prospect of engineering application.
