【摘要】：针对大功率随动试验台中多台永磁同步电机的同步控制问题,同时考虑试验台开放性的要求,提出相邻交叉耦合结构与滑模变结构控制相结合的同步控制策略。结合试验台的机械结构特点,分析比较相邻交叉耦合结构与偏差耦合结构。根据多电机同步系统中同步误差与跟踪误差的控制要求,建立永磁同步电机的状态空间模型,进一步给出多电机同步滑模控制器的设计方法。分析了所设计的同步控制系统的鲁棒性。仿真结果表明,相邻交叉耦合结构与变结构算法相结合的系统其同步误差小于传统的偏差耦合结构与PID算法相结合的系统,受干扰影响变小。对于多永磁同步电机同步系统,相邻交叉耦合结合滑模变结构的控制策略在改善同步性能的同时,增强系统的鲁棒性,简化系统结构,并增强系统的开放性。
[Abstract]:Aiming at the synchronous control problem of several permanent magnet synchronous motors in the high-power servo test rig and considering the requirements of the opening of the test bed, a synchronous control strategy combining the adjacent cross-coupling structure and sliding mode variable structure control is proposed. Combined with the mechanical structure characteristics of the test rig, the adjacent cross coupling structure and the deviation coupling structure are analyzed and compared. According to the control requirements of synchronization error and tracking error in multi-motor synchronous system, the state space model of permanent magnet synchronous motor is established, and the design method of multi-motor synchronous sliding mode controller is given. The robustness of the designed synchronous control system is analyzed. The simulation results show that the synchronization error of the system with the combination of the adjacent cross-coupled structure and the variable structure algorithm is smaller than that of the traditional biasing coupling structure combined with the PID algorithm, and the influence of interference becomes smaller. For the multi-PMSM synchronous system, the adjacent cross-coupling and sliding mode variable structure control strategy not only improves the synchronization performance, but also enhances the robustness of the system, simplifies the system structure, and enhances the openness of the system.
