This paper presents modeling and control of a dual-stage actuator for disk drive servo systems. Parametric modeling of MIMO and MISO dual-stage actuator is presented along with a method to find the parameters. Based on the model, a MISO dual-stage servo algorithm in the form of discrete-time LQG with feedforward control is proposed. Issues in the design of state space dual-stage actuator servo are also addressed. As an example, a MISO servo system is designed for a dual-stage actuator with a piezoelectrically driven microactuator. Through the results of simulation, it is shown that the proposed dual-stage actuator servo system yields considerably improved output disturbance rejection and very fast step response
