Analysis of gyroscope system sliding mode control in a target seeking and tracking process

The study proposed the application of the fuzzy sliding mode for a gyroscope system status control. The state response analysis of the gyroscope system revealed highly nonlinear and chaotic subharmonic motions of2Tduring state formation. The current study discussed the use of tracking control on the sliding mode control and fuzzy sliding mode control of a gyroscope control system. Consequently, the gyroscope system drives from chaotic motion to periodic motion. The numerical simulation results confirm that the proposed controller provides good system stability and convergence without chattering phenomena.

Nonsingular Terminal Sliding Mode

Based on disturbance observer, this paper develops a nonsingular terminal sliding mode control method for uncertain chaotic gyroscope system. Firstly, fuzzy logic system (FLS) is used to estimate the unknown function; then disturbance observer (DOB) is constructed to estimate the mixed disturbance, which consists of the fuzzy estimation error, external disturbance, and dead-zone input error. Subsequently, by using a nonsingular terminal sliding mode function, the control method proposed in this paper can achieve the sliding mode variable approaching a small neighborhood of zero and reduce chattering phenomenon of the tracking error and controller. Finally, comparative simulation results confirm the effectiveness of the method proposed in this paper.

Simulation Results

This paper presents a mathematical model of a gyroscope system with a sliding mode controller. A comparative analysis based on various control algorithms implemented in a controlled gyroscope system installed on a mobile platform (such as an UAV or a homing rocket missile) proved that sliding mode control can be highly effective, especially when external input interferences exist with the kinematic reactions of the mobile platform. A gyroscope system with a sliding mode controller can be used in the optical target seeker systems of precision weapons. The simulation results are provided in a graphical format.
