Sliding mode stabilization of three axis inertial platform

The problem of the improvement of the accuracy in three-axis inertial platform stabilization system with a dynamically tuned gyroscope sensor is considered in the paper. The nonlinear multivariable problem of three-axis inertial platform stabilization is addressed by methods of variable structure control. The decentralized algorithm of sliding mode control design has been worked out and applied for the design of the stabilization system of three-axis inertial platform. The output stabilization errors in each axis have the desired response characteristics via the use of local switched controllers. The results of the simulations of the three-axis inertial platform stabilization system with sliding mode controllers are presented and discussed.<>
