Falcon 9 rocket launched simulator based on MATLAB/Simulink is created to simulate the ascent trajectory starting from initial launch point through to insertion point (reaching orbital speed, altitude, flight path angle). That simulator completed by dynamic models of the Falcon 9 rocket, incorporating its weight and balance model, propulsion model, aerodynamics model, environmental, control and six degrees of freedom (6-DOF) equation of motion. The influenced of aerodynamic forces and moments which acting on the rocket during flight through the atmosphere cause must be designed a attitude control system (pitch control) to stabilize the rocket using Thrust Vectoring Control (TVC). Two cases of Falcon 9 launch simulation will carried out they are open loop system and closed loop control system. Open loop system will discuss about the non-linear system simulation (without aerodynamic moments, longitudinal dynamic stability and full aerodynamics) and also linearized system simulation. Closed loop control system will discuss about the linearized system simulation and implementing the linearization process to the non-linear system (longitudinal dynamic stability). After that we compare the open loop and closed loop result with the Falcon 9 exist data and analyze it.
