MODELING AND ANALYSIS OF A PROTOTYPE OF MULTIPLE LAUNCH ROCKET SYSTEM USING MATLAB SIMULINK

Abstract

This paper presented the control modeling and analysis of the prototype of Multiple Launch Rocket System (MLRS) using Matlab Simulink. The mathematical model was determined using physical law and theoretical foundation of the turning mechanism control system and the elevating mechanism control system. Then, the model was identified in Matlab Simulink and analyzed in open-loop frequency characteristic analysis, closed-loop frequency characteristic analysis, step response characteristic analysis, and sinusoidal response analysis. The simulation results showed a good stability performance for both open-loop control and closed-loop control systems. We observed the fast response of tracking and controlling with the overshoot less than 3% and the steady-state error less than 0.2 Mil.
