Filed: 1987-08-26
Abstract: PURPOSE:To save previous tuning and to follow up the variation of the magnitude of system noise by providing a means which estimates the magnitude of system noise in accordance with output data of a linear system and a means which estimates the magnitude of the variation of the system noise. CONSTITUTION:A means 1 which estimates the state of the linear system in accordance with output data of the system where system noise is varied with time, a means 2 which estimates the magnitude of system noise in accordance with output data, and a means 3 which estimates the magnitude of the variation of system noise in accordance with output data are provided. That is, the magnitude of the variation of system noise is estimated to obtain an estimated value approximating an optimum magnitude of system noise, and thereby, an estimated value approximating an optimum state quantity of the system is obtained. Thus, this adaptive filter follows up the variation of the magnitude of system noise without previous tuning even in case of the change of the magnitude of system noise.
