| 摘 要： | 提出了一种新的电机调速方法,并将其应用到无刷直流电机的驱动控制中.该驱动系统的所有稳定控制器均可用一个独立的Q参数来描述,由该控制器构成的速度环不仅能消除电机脉动转矩引起的速度波动,同时对其他形式的速度干扰也能进行很好的抑制.仿真结果表明:在系统参数发生变化及存在噪声的情况下,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能获得鲁棒稳定性和良好的动态性能.

| Abstract: | A novel speed regulation method is presented and applied in the drive control of BLDCM.The set of all stabilizing controllers for the drive system is characterized by a free Q parameter.The speed loop acts to attenuate any speed variations caused by the motor pulsating torque in the same way it responds to reject any other sources of speed disturbance.Simulation results show that both robust stability and good dynamic performance of the control system due to noise,variation of system parameters and the step change of speed-command/load torque can be achieved using the proposed controller. |
