The Design of Velocity Saturation Servo System Based on Feedback-Linearization and Variable Structure Control
2006
The Non-linear of velocity-saturation of the servo-system is very obviously for great attitude fly of the rocket,which take the great influence of the stability of the rocket's attitude control system.There is difficulty we analysis the non-linear of velocity-saturation of the servo-system with the small-perturbation Theory.So,we accurately linearize the model of velocity-saturation of the servo-system with the method of input-output feedback-linearization,and then the variable structure control is used for the linearization system.In this way,we obtain the robust controller of nonlinear Servo-system.Finally,the simulation results show this means is effective.
