Abstract :
An iterative algorithm based on orthogonal function of parameter identification for distributed parameter system is proposed in this paper, which includes the initial condition and boundary condition to improve identification precision and keep the spatial distributed characteristic. During iterative process, a new uniform method based on block pulse function (BPF) is used to deriving the integral operational matrix, which is a kind of orthogonal function transfer used to transfer the two order partial differential equation to algebra equation. The parameter identification method is simple and easy to compute. The simulation result indicates that this method can meet the demand on real-time and precision of control system.
