Partitioned Discrete Variable Structure Control Strategy and Optimization Method of Four-Axis Gyro-Stabilized Platform
摘要
Abstract
In order to effectively improve the full attitude control accuracy of the four-axis gyro-stabilized platform servo system,aiming at the large angle sway problem of the platform in the process of partitioned variable structure control,an optimized partitioned discrete variable structure control strategy for the control loop of the gyro-stabilized platform is proposed.Based on the analysis of the kinematics equation of the gyro-stabilized platform frame system,the following partitioned discrete variable structure control strategy is given.By analyzing the corre-lation degree between the actuator and the controlled angular velocity,the control strategy of the following parti-tioned discrete variable structure control is optimized.In order to further reduce the switching disturbance in the transformation area,a stable partitioned discrete variable structure control method is proposed based on the follow-ing partitioned discrete variable structure control,which integrates and optimizes the variable structure area,and ef-fectively avoids the shaking caused by the motion state switching between different areas.The simulation results show that,compared with the control strategy before and after optimization,the swaying angular velocity of the platform in the X direction decreases by 63.5%,the swaying angular velocity of the platform in the Y direction de-creases by 84.5%,the swaying angular velocity of the platform in the X direction decreases by 29.0%,and the swaying angular velocity of the platform in the Y direction decreases by 57.3%,which effectively reduced the plat-form sway in the switching process of the variable structure control and improves the control accuracy.关键词
