| 针对内置式永磁同步电机弱磁控制在弱磁程度较深时，受到电机参数摄动和外部扰动时会造成电压环输出、转矩和电流脉动增大，转速收敛过慢等问题，提出一种转速-电压环反馈超螺旋非奇异快速终端滑模控制器(FST-NFTSMC)的深度弱磁控制方法。为了减少弱磁控制对系统模型的依赖，根据内置式永磁同步电机在参数摄动时的数学模型，构建电压环超局部模型，并结合转速环超局部模型建立转速 电压环超局部模型。基于此超局部模型，结合反馈超螺旋算法和非奇异快速终端切换函数设计转速-电压环FST-NFTSMC，同时建立改进滑模扰动观测器对系统存在的未知部分进行估计，并前馈补偿给FST-NFTSMC，进一步提高系统的鲁棒性和控制精度。仿真和实验表明，与传统PI控制相比，该方法在无弱磁区、浅度弱磁区和深度弱磁区的收敛速度上分别提高了66%、40.6%和28.6%，稳定性更好，转矩和电流脉动更小，证明了该方法在弱磁控制上能有效抑制电压环受到扰动后输出的抖振以及提高转速响应速度。 |

| For flux weakening control of the internal permanent magnet synchronous motors, when the degree of flux weakening is deeper, the motor parameter perturbation and external disturbances will cause the voltage loop output, torque and current pulsation to increase, and the speed convergence is too slow. A speed-voltage loop feedback super-twisting non-singular fast terminal sliding mode controller (FST-NFTSMC) is proposed for deep flux weakening control. To reduce the dependence of flux weakening control on the system model, the voltage-loop hyperlocal model is constructed according to the mathematical model of the built-in permanent magnet synchronous motor during parameter perturbation. And it is combined with the speed loop hyperlocal model to establish the speed-voltage loop hyperlocal model. Based on this hyperlocal model, the speed-voltage loop FST-NFTSMC is designed by combining the feedback super-twisting algorithm and the non-singular fast terminal switching function. At the same time, an improved sliding mode disturbance observer is built to estimate the unknown part of the system and compensate for the estimated value feedforward to FST-NFTSMC, which further improves the robustness and control accuracy of the system. Simulation and experiment show that compared with the traditional PI control, the convergence speed of the proposed method in the no flux weakening region, shallow flux weakening region, and deep flux weakening region is improved by 66%, 40.6%, and 28.6% respectively. It has better stability and fewer pulsations of the torque and current, proving that the method in the flux weakening control is effective in suppressing the output jitter after the voltage loop is perturbed as well as improving the speed response. |
