摘　　要：针对电梯用永磁同步电机(PMSM)建模的复杂性及高性能控制的需求,设计了基于特征模型的抗扰动自适应控制算法。在采用i_d=0的矢量控制下建立系统的二阶特征模型,设计了速度环相应的积分黄金分割自适应控制。针对电梯运行时的负载扰动,设计了一种转矩观测器,将转矩观测量补偿到电流环输出中。仿真结果表明,基于特征模型的抗扰动自适应控制具有良好的稳态精度及鲁棒性;进一步结合电梯速度曲线的仿真研究,验证了其用于电梯PMSM调速系统的可行性。Considering the model complexity of elevator permanent magnet synchronous motor(PMSM),a characteristic model-based anti-disturbance adaptive control was adopted to achieve high precision control needs.A characteristic model was established by used the i d=0vector control.Based on the characteristic model,a golden-section adaptive control was applied to the speed loop.A torque observer was designed to add torque quantity into the current loop for compensation.Simulation results showed that the characteristic model-based anti-disturbance adaptive control had good steady-state accuracy and robustness.Combined with the elevator speed curve,the simulation results verified that the control algorithm applied to the elevator with PMSM control system was feasible.
