摘要：

An iterative optimal excitation signal design method is presented to select an optimal signal for closed-loop system identification. The control performance criteria is used as the criteria for optimizing excitation signal, and the robust stability of closed-loop identification and power spectrum constraints for excitation signal, control signal and output signal are considered. Based on these, the paper formulize optimal excitation signal design problem and solve power spectrum of excitation signal. Finally, an iterative method is used to solve optimal excitation signal and identify system model. Simulation result shows that model quality by closed-loop identification is improved by using excitation signal optimal method proposed in this paper.
