The two-dimensional correction of rockets with fixed-canard has received wide attention. How to design an accurate correction way becomes the focus and difficulty. Hence, this paper mainly studies fixed-canard control mode, and built the fixed-canard control force module. By using modular thinking, the whole model is divided into sub modules with different functions, then each module is integrated into two-dimensional correction trajectory simulation model of rocket. Being based on the module, the uncontrolled and the controlled trajectory are simulated respectively. Simulation results showed that the uncontrolled trajectory preferably accorded with the trajectory characteristics of the actual rocket. At the same time, the simulation of controlled trajectory demonstrated that with the fixed-canard as the actuator, using the MPN (modified proportional navigation control algorithm) to correct the projectile could greatly improve the strike accuracy of the projectile.
