| Abstract: | The active vibration control is becoming an effective mean to solve the vibration control problems of the aerospace and other fields.For its light and swift response,piezoelectric material occupies an important position of vibration engineering.In order to verify the feasibility,the simply-supported beam was predigested as a three degree of freedom system,and then the differential equation and state space equation were set up.According to the independent modal space control（IMSC）,the control law was design.The vibration of beam under an initial disturbance and continuous incentives was controlled.The result proves that active vibration control of system is efficient. |
