INVESTIGATION OF LINEAR QUADRATIC REGULATOR DECENTRALIZATION PROPERTIES FOR A CLAMPED-CLAMPED BEAM
Original language description
Heavy computational burden is imposed on centralized controllers when dampening vibration for large-scale flexible structures. For homogeneous flexible structures, the structure of controllers shall be investigated to simplify the control loop design. Inthis work, firstly a linear-quadratic regulator (LQR) is designed for a normalized infinite-dimensional beam model under a clamped-clamped boundary condition, to demonstrate the decentralization property of the controller. A finite element model (FEM) based on Euler-Bernoulli beam theory is then considered, an LQR is designed with distributed actuators and isolated point-actuators respectively, providing all the states can be measured. Control simulations have shown a decentralization property in bothcases, which motivates a decentralized controller inherited from the LQR design. Simulation results have shown that the performance of decentralized controller and the LQR is comparable.
