Paper Abstract

In this research, a real-time simulation of full state- derivative feedback control using acceleration measurements is presented. A new optimal control design algorithm based on non-standard performance indices in the 'Reciprocal State Space' framework is employed to design controllers and observers. A piezoelectric material (PZT) laminated cantilevered steel beam with an accelerometer is selected as a test bed. The system is modeled utilizing a multi-layered integrated finite element method with four degree of freedom, one-dimensional, bending elements. The resulting model, presented in generalized coordinates, is transformed to real orthogonal modal coordinates and a reduced order model is developed. Simulated results are provided in multiple formats.
