The principle of the Kalman filter is discussed briefly. The unified diagram of a driving system bassd on physical paramenters of Y7250 screw grinder is estabilished. Then, the sixth梠rder state equation of this system and the parameter matrix which is required in Kalman filter design is derived. Based on these, the computer simulation software can be programmed and a closed control system with random disturbance is formed. All of the additive noises of the system are recorded from the real machine as pseudorandom disturbance simulation. The result of the simulation not only proves that the precision has been improved but also shows that the mean square error and the filter gain are stable. Therefore, the software is simplified and becomes more suitable for real-time control.
