Abstract

Design method of eigenvalue assignment based on standard characteristic polynomial, as well as mathematical solving process of the method, is proposed in this paper so as to resolve the uncertainty of ideal eigenvalue choice in modern control theory and the difficultly in engineering implementation of modern control system design methods. Longitudinal stability holding control system of an aircraft was designed and simulated by employing proposed method. Dynamic character and robust performance simulation of the system are given. Simulation results show that the method achieves the control quality and has better robustness than another method. There is only one design parameter which is easy to calculate. So, the method is characterized as simple design, logical structure, easy programming and convenient for engineering implementation.
