摘要：

A piezoceramic stack-mass positioning system was tested with different frequencies and voltages for its response to different input conditions. It is observed that the response of the positioning system varied with different input conditions. A technique is developed to compensate for this variation by the use of an open loop compensator. This open loop controller is able to compensate for the phase lag inherent in the stack-mass system, thereby improving its dynamic response and position resolution.
