摘要
为使永磁同步电机位置跟踪控制系统具有无超调快速响应性能和较强的系统参数、负载鲁棒性,提出一种基于模型自适应补偿的非线性组合反馈控制方法。针对高增益线性反馈与超调的矛盾性,以非线性反馈控制器为第二控制器,实现无超调快速跟踪参考位置,并讨论了存在输入受限情况下离散非线性组合反馈控制在吸引域内的稳定性条件。针对一般非线性组合反馈控制的参数和负载扰动自适应差的问题,采用仿射投影模型自适应补偿算法提高系统鲁棒性。通过仿真和实验表明该新型组合控制方法除了具有很好的动静态性能,还具有良好的参数、负载鲁棒性,适用于永磁同步电机高性能位置跟踪控制。
In order to meet the requirement,namely rapid non-overshoot response and good robustness for parameters and load,a new composite nonlinear feedback（CNF） control based on model compensation is proposed for permanent magnet synchronous motor（PMSM） position tracking control system.Considering the contradictions high-gain linear feedback with overshoot,a second nonlinear feedback controller was used to realize rapid and non-overshoot response of system.And the stability of discrete composite nonlinear feedback with input saturation was also deducted respectively in detail.With poor robustness for parameters and load of normal CNF control,a model compensation algorithm offered by the affine projection was adopted.Finally by means of simulation and experiment show that the new composite control method has very good dynamic and static performance,furthermore excellent robustness for parameter and load.And it is suitable to realize high performance position tracking control for PMSM.
