氣浮臺垂向自動調節(jié)系統(tǒng)設計及姿態(tài)穩(wěn)定控制
[Abstract]:In order to better explore and utilize space resources, various spacecraft have been created to carry out corresponding missions. However, the space environment is different from the ground environment, vacuum, radiation and microgravity conditions put forward strict requirements for spacecraft. Because of the complexity of space mission and the high cost of operation, people have to test the spacecraft in the ground, so the all-physical simulator emerges as the times require. The full physical simulator can simulate the state of spacecraft in orbit completely on the ground, which greatly reduces the test cost before the spacecraft carries out the mission, and can also improve the performance of complex tasks. In order to shorten the preparation time, optimize the initial state and improve the control effect, the vertical position control and attitude stability control of the six-degree-of-freedom air flotation platform are studied. Firstly, the working process of the vertical air bearing is studied, and the resistance factors of the air gap to the movement of the air bearing are analyzed, and the unstable factors of the air source input are also analyzed. Select specific implementing mechanism and model. The air bearing is abstracted as a variable mass air chamber and modeled, and the general model of the vertical position automatic control system is established based on the model. Through simulation, the feasibility of the model is verified and the characteristics are analyzed. Secondly, two-valve subsection control scheme is adopted. According to the control requirements, the parameters of the piecewise control are analyzed, and the logic and program of the piecewise switch are designed. Then, according to the proposed double valve control scheme, the digital incremental PID controller is used in the fine tuning stage, and the fuzzy PID controller is used in the coarse tuning stage. In rough tuning control, the fuzzy rule of empirical tuning is abandoned, the fitness function is designed, the main operators in genetic optimization algorithm are improved, and the rules are optimized. Then the control scheme is simulated synthetically. Thirdly, the attitude stability control of the onstage in six degrees of freedom test preparation stage and docking stage is studied. The error quaternion is used to establish the attitude model of the air floatation platform. A novel sliding mode switching function of a nonsingular fast terminal is designed for the demand of suppressing external interference and fast stability and the approach control law is obtained by using the backstepping method. The control algorithm is verified by numerical simulation. Finally, hardware selection, hardware and software system construction. The man-machine interface is designed, the control program is written and the proposed control scheme is tested by engineering experiments.
