• This paper presents an effective method for redesign of the M-V third stage attitude control algorithm. The fundamental aspect of the redesign is featured by introduction of an integral term into the controller in order to reduce steady state error caused by offset of the centre of gravity of the vehicle and thrust axis misalignment. The proposed method is based on the idea to utilize the existing controller as the inner loop (attitude angular velocity) controller of the cascade control. Adding the velocity-position integrator into the controller leads to the desired integral characteristics. The dynamic character of the entire closed syetem and its robustness in the gain and phase margins are investigated for five representative controllers, which are switched at the specified time marks, and corresponding nominal and deviated dynamic models.
