基于自抗扰的多电机转速同步系统传感器故障切换容错策略
|
Abstract:
摘要： 以多电机转速同步系统为对象,针对实际负载不确定及未知干扰对系统的影响,在速度外环采用自抗扰控制技术(ADRC),以提升同步控制性能;基于无速度传感器矢量控制原理,在电流内环采用扩张状态观测器(ESO),通过对含有转速的扩张状态的观测,进而实现对转速的估计;针对转速传感器的故障,对ESO估计转速与实际转速的残差进行分析,进而进行故障诊断;为保证故障系统安全平稳运行,在由实测转速向估计转速切换时,通过设计具有故障诊断可靠性评价的自适应柔性切换策略,保证了切换时的平滑过渡。 仿真试验验证了所提方法的有效性。
Abstract: Focusing on multi-motor synchronous control system which was susceptible to variable load and random disturbance, an active disturbances rejection control(ADRC)technique was used to improve the synchronous performance. Based on the principle of sensorless vector control, an extended state observer(ESO)was used in the current loop to obtain the estimated speed with observation of its extended state. The residual signal between actual speed and estimation speed was analyzed to realize fault diagnosis. In order to ensure the safe operation of the fault system, a flexible adaptive switching strategy based on fault diagnosing evaluation of reliability was proposed to ensure smooth transition in case of requiring. Simulation results showed the effectiveness of the proposed method
