研究了具有随机时延的双线性开关磁阻电机在通信网络上的协同跟踪控制问题。考虑到复杂工业过程中双LSRMs的时空约束关系，提出了基于网络化运动控制方法的协同跟踪控制方案。利用李雅普诺夫理论和时滞系统方法，从两电机相对位置误差出发，得到了网络化双LSRM的稳定性条件和控制器设计方法。将4种不同的分配方案与2种外部控制信号相结合应用于双LSRM协同跟踪控制实验平台，验证了所提方法的有效性。在绝对位置基准输入信号为3 mm时，最大稳态相对位置误差可达0.104 mm以内;在振幅为8 mm、频率为0.2 Hz的正弦基准下，最大绝对相对位置误差可达±0.46 mm以内。
This paper investigates the collaborative tracking control for dual linear switched reluctance machines (LSRMs) over a communication network with random time delays. Considering the spatio-temporal constraint relationship of the dual LSRMs in complex industrial processes, the collaborative tracking control scheme is proposed based on the networked motion control method. The stability conditions and the controller design method for the networked dual LSRMs are obtained from the two motors relative position error by using Lyapunov theory and delay systems approach. Four different allocation schemes combined with two kinds of external control signals are applied onto the collaborative tracking control experiment platform of the dual LSRMs to validate the effectiveness of the proposed method. The maximum steady-state relative position error within 0.104 mm can be achieved under the constant absolute position reference input signal of 3 mm, and the maximum absolute relative position error within ±0.46 mm can be achieved under the sinusoidal reference of 8 mm amplitude and 0.2 Hz.
