摘要：本文将无源性控制应用于两相混合式步进电机的速度控制系统中，在哈密顿模型下建立了基于状态误差模型的无源性速度控制器，针对实际运行时负载扰动未知的问题，设计了负载扰动观测器。仿真和实验结果表明无源性控制对两相混合式步进电机的速度控制具有较好的鲁棒性，良好的动态和稳态性能。

Abstract: In this paper, the passive based control was applied to speed control system of a two phase hybrid stepping motor. Under the Hamiltonian model, the passive based speed controller was established in the way of state error model. Moreover, a load disturbance observer was designed for compensating unknown load disturbances. Simulation and experimental results demonstrate that the proposed algorithm can provide a good dynamics and precious speed tracking ability besides robustness on load disturbances for the hybrid stepping motor system.
Key words: passive based control; two phase hybrid stepping motor; speed control; disturbance observe
