【Abstract】 To deal with the problems of delay, intensive inertia and serious nonlinearity in a centrifuge system, the control system of the centrifuge is developed in this paper. The structure of the control system is presented. An adjustable PID control algorithm is used in the centrifuge. After getting present information on the state of the centrifuge by some sensors, we inquire the table by software. At the same time we get accurate PID controlled variables. The effectiveness of the proposed method is demonstrated through experiments. The controller can realize the tracking of command signal and has a great practical value.更多还原
