Application of Variable Structure Control in Missile Electromechanical Actuator System

Parameter variation and load disturbance will have great influence on the performance of missile electromechanical actuator system and further on the performance of the entire missile system during the missile flight process. To solve this problem, a variable structure control system for missile electromechanical actuator system was proposed in this paper. To verify the proposed control scheme, simulation has been performed for different system parameters. Simulation results indicate that the proposed variable structure control method can provide the properties of robustness to load and environment disturbance and insensibility to parameter variation. So it is very suitable for complicated and variable flight environment of missile.
