Balanced Proper Orthogonal Decomposition and Its Application on Order Reduction to Aeroelastic Models of Aircraft Wing
This work applies balanced proper orthogonal decomposition (BPOD) to reduce the order of aeroelastic control system. The BPOD method is a combination of the proper orthogonal decomposition (POD) and balanced realization theory and can overcome the limitations caused by high dimensional characteristic. The theoretical derivation and order reduction process of BPOD are presented first. Then, the proposed method is applied to the reduce the order of the aeroelastic model of a three-dimensional wing. Based on the analysis of numerical simulation results,it is shown that, while keep the input-output relationship, BPOD is able to effectively reduce the system order, as well as the computational cost, and is very suitable for aeroelastic control systems.
