Stability And Controllability Analysis On Linearized Dynamic System Equation Of Motion Of Lsu 05-Ng Using Kalman Rank Condition Method

This paper discusses the stability and controllability of the dynamic system of the LAPAN Surveillance UAV 05-NG (LSU 05-NG) aircraft equation. This analysis is important to determine the performance of aircraft when carrying out missions such as photography, surveillance, observation, and as a scientific platform to test communication-based on satellite. Before analyzing the dynamic system, first arranged equations of motion of the plane which include the force equation, moment equation, and kinematics equation. The equation of motion of the aircraft obtained by the equation of motion of the longitudinal and lateral dimensions. Each of these equations of motion will be linearized to obtain state-space conditions. In this state space, A, B, and C are linear matrices that will be obtained in the time domain. Stability analysis using eigenvalue method and controllability analysis using Kalman Rank Condition method. The results of the analysis of matrices A, B, and C show that the dynamic system in the LSU 05-NG motion equation is a stable system on the longitudinal dimension but the lateral dimension on the unstable spiral mode. As for the analysis of the control of both the longitudinal and lateral dimensions, the results show that the system is controlled.
