Abstract :
In this paper, the characteristics of an electric shaker are analyzed first. A fuzzy PID control rules is established according to the nonlinear characteristics. The controller has a feedback - feedforward structure, which realizes a tracking control of acceleration for the electric shaker. Experimental results show that the controller works stably and obtained 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.
