Aiming at increasing the range of Guided Rockets considering whole phase multiple constraints,an optimal trajectory design and guidance method was proposed. The optimization model of rockets was established,considering the range as the optimization index,an optimal trajectory design method was proposed. Designing a LQR-based approach for trajectory guidance method,the multivariable tracking of optimal trajectory was achieved containing height,velocity and flight path angle. Simulations were made,which demonstrate that the trajectory range significantly increased,the optimal trajectory is tracked exactly by the proposed guidance law.
Key words: rockets; optimal trajectory design; multivariable tracking
