基于PBC的交流电动机控制器的设计与仿真

为能够准确得到以交流电动机驱动的航空液压泵性能的测试结果,必须保证电机调速控制具有良好的鲁棒稳定性。本文针对交流电机有难以避免的时变、强耦合等非线性特性,采用无源性控制为主的调速控制策略,提出能量成形的无源性控制器的设计方法。通过仿真,说明无源性控制器可实现对速度的调节和跟踪,得到的转速控制结果不仅响应快,而且是稳定的,其效果很好。

Design and Simulation in AC Motor Controller Based on Passivity-based Control

The aim of the research is to ensure the robust stability of output rotating speed of the AC motor so as to get better test results,which could account for the of Aero Hydraulic Pumps.In allusion to the AC motor has unavoidable nonlinear characteristics such as time varying and close coupling,the PBC（Passivity Based Control） strategy was taken as leading speed adjusting control rule.A PBC energy-balancing（EB-PBC） approach for the controller is brought forward.The simulation shows that passivity controller can achieve the speed regulation and tracking,and the speed control results is fast response and stable.
