Abstract

An oscillation control system includes an actuator, a sensor unit, and a control module. An actuator includes at least one piezoelectric material coupled with an electrode. The sensor unit is located on the actuator and is configured to detect an acceleration value of deformation of the actuator. A control module includes an operational unit and a gain unit. The operational unit generates an operational result according to the acceleration value and conditions of the actuator. The gain unit is coupled to the operational unit and the electrode and is configured to convert the operational result into a control signal which adjusts the actuator. An oscillation control method includes using a reciprocal state space system to proceed with closed-loop control of a state derivative feedback. The reciprocal state space system is represented by a plurality of equations.
