Research and Implementation of General Filter Algorithm Based on Kalman Computation Framework

A variety of filters are unified into Kalman computation framework,which consists of two processes: time prediction and measurement update,and on the basis of which open-closed principle in software design theory is applied to conduct researching on general filter algorithm.State-space model and data structure design of Kalman filter computation framework,which were characterized by better flexibility,expandability and insertability,were put forward,thus simplifying the construction and implementation of the new filter algorithm.A demo programme using the general filter algorithm was given at the end.
