摘要
This paper presents a digital acceleration controller for sinusoidal tests using switching mode power amplifier (SMPA). The proposed method is based on two control loops: one for the shaker's acceleration control and another for the SMPA output voltage control. A simple and efficient voltage-controlled method is used in the SMPA. The acceleration controller consists of feedback controller, a feedforward controller and a robust disturbance feedforward controller. Experiments show that the proposed system is capable to achieve excellent acceleration and robustness in the closed loop control from 20Hz to 200Hz.
