摘要：We studied a precise positioning system for a spinstand with a linear actuator and a digital controller. The linear actuator was composed of an air bearing and a linear voice coil motor. The digital controller was consisted of a digital signal processor. We tested a reference response and an impulse disturbance rejection for the linear actuator by using only a feedback controller. However, when we applied only the feedback controller for the linear actuator, there was a tradeoff between the reference response and the impulse disturbance for its performance. We applied a two-degrees-of-freedom (2DF) control which was consisted of a feedback controller and a feedforward controller. The feedback controller suppressed the disturbance and the feedforward controller improved the performance of the reference response. We investigated the effect of the controller from the simulations and the experimental results.
