Vibration control using the non-model based algorithm

Abstract

A study on the vibration control of a steel beam and plate using electromagnetic actuator has been performed. The system is assumed time-varying so that the system model is considered unknown, therefore the mathematical model of the control structure is not used in the control algorithm. The algorithm only needs the vibration displacement data in real-time. The control algorithm is based on PID with an adaptive function to the change of dynamic characteristics of the structure. The vibration suppression or excitation was successfully achieved by using a test setup including a cantilever beam, a laser displacement sensor, electromagnet and microcomputer loaded with the developed control program.
