The longitudinal blended dynamic model of missile with lateral thrust and aerodynamic control was developed according to the separation design of control allocation and control law.A kind of new optimal control allocation algorithm was proposed.Trust region method with global convergence was applied to solve constrained quadratic programming problem
without requirement of positive definiteness for Hesse matrix.A new allocation strategy was proposed according the position of lateral jet engine.The optimal ignition mode was selected by lateral thrust subsystem.Control error caused by the uncontrollable engine thrust would be compensated by aerodynamic subsystem.Simulation results show that the optimal allocation is realized in longitudinal control of missile by tracking the command steadily and quickly.The results are acceptable.
