摘要
针对高性能的表面式永磁同步电机(SPMSM)调速系统,考虑电机实际运行过程中逆变器非线性因素对传动系统的影响,推导出考虑逆变器的SPMSM系统统一端口受控耗散哈密顿数学模型.基于能量成形方法和端口受控耗散哈密顿系统原理,设计SPMSM驱动系统的无源控制器,利用带扩张状态观测器的自适应滑模控制设计速度调节器,得到轴期望的电流并实现转速的估计,逆变器非线性扰动由扩张状态观测器进行补偿.仿真结果表明,所提出方法实现了较高的速度估计精度,使调速系统具有优良的动、静态性能.
The unified PCHD modeling with inverter is established for the high performance of the speed control system of SPMSM. The passive controller of the SPMSM drive system is designed based on the interconnection and damping assignment of the energy-shaping method and port-controlled Hamiltonian systems with the dissipation（PCHD） theory. The speed regulator is designed by using the adaptive sliding mode method with extended state observer（ESO） in order to get desired q axis current and estimated speed, and the nonlinear disturbance caused by the inverter is compensated by using the extended state observer. The simulation results show that the proposed method realizes the veracity of speed estimation, so that the system has satisfactory dynamic and static performance.
