| 摘 要： | 为了提高直流电动机调速系统的性能,提出了一种基于负载观测的直流电动机调速系统无源控制实现方法。负载观测器通过检测直流电动机的电枢电流和转速重构当前工况下的负载转矩。基于系统的端口受控耗散哈密顿模型,根据负载观测器估计的实时负载,运用互联与阻尼分配的无源控制方法,并采用参数切换进一步优化控制策略,实现对给定转速的快速、稳定跟踪。仿真结果表明采用所设计的无源控制策略,能使直流电动机调速系统具有良好的动、静态性能与较强的鲁棒性。

| Abstract: | In order to improve the performance of DC motor drive system, a passivity-based control (PBC) method for DC motor drive system based on load observer is proposed. The load observer reconstructs the load torque by detecting the armature current and speed of DC motor. Based on the port-controlled Hamiltonian system with dissipation (PCHD) model of DC motor drive system and the observed load, use the interconnection and damping assignment passivity-based control (IDA-PBC) methodology with parameters conversion to track the given speed quickly and stably. The simulation results show the DC motor drive system using the proposed PBC method has good dynamic and static performances and good robustness. |
