Applying standard characteristic polynomial method to designing lateral-directional mode control of flight control system

Sections 1 through 5 of the full paper explain fully the application mentioned in the title. Their core consists of: (1) we use the signal-input mode control method to equalize the feedback matrix of multi-input mode control with the product of two first-order matrixes; thus the multi-input mode control problem is converted into the signal-input mode control solution; (2) we solve the matrix of a multi-dimensional controller and configure the characteristic root to the desired position by selecting the value of its characteristic parameter, thus implementing the control of the flight control system; (3) we apply our standard characteristic polynomial method to designing the lateral-directional mode control of the flight system of a certain aircraft to achieve its stability and then analyze the robustness of the mode control system and the effects of different parameters on the performance of the aircraft. The simulation results, given in Figs. 3, 4 and 5, and their analysis show preliminarily that: (1) our standard characteristic polynomial method can design effectively the lateral-directional mode control of the flight control system of the aircraft; (2) the flight control system has good robustness; (3) a large range of characteristic parameters are available for selection.
