摘要
An actuator control system, mechanical testing system, and method for adaptive control of an actuator of a mechanical testing device is provided. The method includes applying a mechanical load to the specimen with the actuator, resulting in receiving a load sensor signal from a load sensor and a displacement sensor signal from a displacement sensor, deriving lumped dynamics of the mechanical testing device by analyzing a phase and magnitude relationship between a current command of a motor of the mechanical testing device and a resultant deflection of the specimen, and controlling the actuator based on the derived lumped dynamics of the mechanical testing device such that the controlling results in a stable motion.
