【摘要】：考虑逆变器非线性因素对调速系统的影响,从能量和鲁棒性的角度研究了表面式永磁同步电机(SPMSM)调速系统。首先推导了包含逆变器的SPMSM系统统一端口受控耗散哈密顿系统(PCHD)数学模型,基于能量成形方法和PCHD原理,设计了SPMSM调速系统的无源控制器,简化了控制算法,保证了系统全局稳定,逆变器非线性扰动由扩张状态观测器进行补偿。针对速度外环响应速度慢、鲁棒性差的问题设计了非奇异快速终端滑模速度控制器并得到q轴期望的电流。仿真和实验结果表明,所提控制方法使转速跟踪速度快、鲁棒性强,提高了整个系统的动静态性能。
[Abstract]:Considering the influence of inverter nonlinear factors on the speed regulation system, the (SPMSM) speed regulation system of surface permanent magnet synchronous motor (PMSM) is studied from the point of view of energy and robustness. Firstly, the (PCHD) mathematical model of unified port controlled dissipative Hamilton system of SPMSM system including inverter is derived. based on the energy forming method and PCHD principle, the passive controller of SPMSM speed regulation system is designed, which simplifies the control algorithm and ensures the global stability of the system. The nonlinear disturbance of the inverter is compensated by the extended state observer. In order to solve the problem of slow response speed and poor robustness of the speed outer loop, a nonsingular fast terminal sliding mode speed controller is designed and the expected current of the Q axis is obtained. The simulation and experimental results show that the proposed control method makes the speed tracking speed fast and the robustness strong, and improves the dynamic and static performance of the whole system.
