惯性变化时无刷直流电机的鲁棒控制器设计

Robust Controller Design for Brushless DC Motor

为了获得良好的无刷直流电机调速性能,提出了一种基于Q参数化理论的控制器设计方法。该方法的主要特点是被控对象的所有稳定控制器均可用一个独立的Q参数来描述。仿真结果表明:在系统参数发生变化的情况下,在参考速度和负载转矩发生改变时,本文提出的控制策略都具有很好的响应特性。

In order to achieve good speed regulation performance, a novel controller design method based on Q-parameterization theory is presented. The main characteristic of this method is that the set of all stabilizing controllers can be characterized by a free Q parameter. Simulation results show that good response of the control system due to variation of system parameters and the step change-of-speed command / load torque can be achieved using the proposed controller.
