ANALYSIS OF VIBRATION DETECTION USING ACTIVE CONTROLLER IN THE SMART CANTILEVER COMPOSITE BEAM WITH LQR AND FUZZY TECHNIQUES
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2018, Vol 8, Issue 4
Abstract
Vibration is the major problem in light weight composite structures. Active vibration methods are effective to control the vibration. In this work, vibration control using active controller for an E-Glass/Epoxy Cyanate laminated composite beam, which uses patches of piezoelectric ceramic patches as smart sensors and actuators were tested and analyzed. The combination of Linear Quadratic Regulator (LQR) with Kalman filter and Fuzzy technique gives greater Region Of Convergence (ROC). The control is based on the proximity output and the previous output. This combination gives best optimization in the output, hence the settling time is good, and the system gives fast and stable output response. The entire Vibration Reduction System (VRS) consists of a Data Acquisition module, composite beam with Piezo electric ceramic sensor and actuator. This VRS setup is simulated using Matlab/Simulink and the output analysis shows that, this system reduces the vibration efficiently compared to the previous methods.
