Optimal Control for the Fuser System of Electro-photographic Printer

摘要

In this paper, a linear quadratic Gaussian controller is proposed to achieve the robust temperature stability of the fuser system against measurement noise and system disturbance. The proposed controller is fitted to replace the PI controller and relative mathematical derivation is described. The system is implemented using MATLAB and SIMULINK with adding the noise and disturbance. Improvement of performance is verified by comparison with conventional PI controller results on several key factors of the fuser system.
