Active Vibration Control Applying Fuzzy Logic in a Flexible Rotor Using Electromagnetic Actuators

In the last few years, new methods to perform active vibration control were proposed and developed with the purpose of handling with several dynamic problems. These researches are motivated by the necessity of a safer and more efficient performance in the operation of mechanical systems (industrial applications). There are several types of actuators available for the active vibration control, the current work is dedicated on the Electromagnetic Actuator. This actuator uses electromagnetic forces to control the rotor without mechanical contact. And it is represented by a non-linear model, which justifies the control by Fuzzy Logic. In this work, the aim is to attenuate rotor system vibration by Fuzzy Logic based in Takagi-Sugeno model, the control is achieved using the linear quadratic regulator. Finally, the simulation results demonstrate efficiency of the methodology, which can be seen in the reduction of vibration amplitude.
