Finite Element Methods (FEM) play an important role in modelling of complex systems. Models generated from FEM are of very high dimension and are difficult to handle for control system design. In this paper, an algorithm is presented that converts a system generated from FEM into the state space model of an interconnected system, thus vastly reducing the complexity of synthesizing a distributed control strategy. A simple cantilever beam problem is used as an example to illustrate the proposed method. A state space representation of this system is obtained through FEM analysis. This model is converted from lumped state space form to interconnected form. A decentralized controller is then designed using a homotopy approach.
