The steps of rocket development require very details preparation before a flight test is carried out. The development of 200 mm caliber rockets with canards is intended to accomplish the trajectory correction mission so that the rocket flies according to the trajectory predictions that has been determined in its design. A comprehensive simulation is conducted using the Software in the Loop Simulation (SILS) method followed by Hardware in the Loop Simulation (HILS), then utilize one of the optimal types of control, Model Predictive Control (MPC) so that canard control on trajectory correction can be achieved. The simulation was carried out in 2 steps, first step based on the original thrust profile of the 200 mm caliber rocket motor design, and the second step optimized with 2 times of the thrust profile. This is intended to get a longer control time because in this simulation the control range is only limited to speed Mach 1. With 144 s (93.5% total flight time), the MPC can freely and successfully control the trajectory correction, even being able to maneuver to get a shorter or longer flight distance than the original trajectory. Also maneuver to turn right or left, according to the control roll. And it is possible to become a guided missile if adds an outer loop program for navigation.
