Through the analysis of the nonlinear characteristics of the electric shaking table, a composite controller is created, based on the theory of fuzzy and PID control and feedhack-feedforward structure. The controller realizes a tracking control of acceleration for the electric shaking table. Experimental results show that the controller works stably and obtains the satisfying control effect. Moreover, in order to decrease system's tracking error, the change rate of input variable is taken as a control variable, this strategy is suitable for a class of tracking control systems in which the input changes rapidly.
