| Abstract: |
| Objective To develop a time domain method for the study of measurement noise impact on the control efficiency of piezoelectric vibration control system based on thermal analogy method. Methods The state-space model of the piezoelectric structure was established firstly and certain control strategy was selected to design the controller, then the close-loop stimulation of the control system was made considering the issue of interruption of the control system by noise to investigate the influences of different noise levels on the piezoelectric vibration control system. Results Simulation results demonstrated that 50 Hz industrial frequency noise had little influence on the control effect when the neural network control strategy was used to implement vibration control. Conclusion The method can deal with various noises, and rapidly and visually show the noise influence on control effect. |
