主動磁懸浮軸承滑模變結構控制器的研究
[Abstract]:With the development of industry, it is more and more difficult for traditional bearings to meet the requirements of high performance and low energy consumption. Active magnetic bearing (AMB) has many advantages such as no mechanical loss, no friction, no lubrication, low noise, adjustable rigid damping, high theoretical speed and so on. It has gradually become an ideal substitute for traditional bearings. However, the active magnetic bearing system is a multi-input and multi-output system with strong nonlinearity and high coupling. The traditional PID control method can not meet the requirements of the stability and dynamic characteristics of the system. Therefore, the sliding mode variable structure control strategy is used to study the controller of active magnetic bearing. The main work is as follows: the development and application prospect of active magnetic bearing are summarized, the basic structure and working principle of active magnetic suspension bearing are studied. The single-degree-of-freedom active magnetic bearing system is studied and its mathematical model is established. According to the discrete sliding mode variable structure control theory, the corresponding controller is constructed, and the program is written by MATLAB. The control effects of discrete sliding mode variable structure controller and traditional PID controller are simulated and compared. On the basis of the research of single degree of freedom magnetic bearing, the five degree of freedom active magnetic bearing system is systematically studied. Firstly, the equation of motion is analyzed and the mathematical model of the system is established. Aiming at the complexity of 5-DOF active magnetic bearing system, the decoupling study is carried out, and a controller based on multi-input and multi-output integral sliding mode variable structure control is designed. Finally, the simulation results show that the proposed control strategy has better dynamic performance and robustness than the traditional PID control method.
