摘　　要：高精确度多感应电机同步控制是现代制造业和传动系统最关键的问题之一。感应电机是一个多变量、非线性对象,而现有的多电机同步控制策略多采用简化的一阶感应电机模型,难以满足高精确度的同步控制要求。基于转子磁场定向下的感应电机数学模型,采用相邻交叉耦合控制结构,利用滑模变结构控制方法设计了一种结构简单的多感应电机同步控制策略,并采用一种简单的方法消除抖振现象。与相邻交叉PID控制策略进行的对比仿真表明,该控制策略具有较高的同步精确度和较强的鲁棒性。High precision multi induction motor control is one of the key issues in modem industry and motion control field. Induction motor model is multi-variable and nonlinear, while the simplified one-order induction motor model is widely used in current muhi-motor control area, which cannot satisfy the requirements of high precision multi-motor control. Sliding-mode control method was adopted incorporating adjacent cross-coupling control structure in the proposed control strategy based on 4-order field-oriented induction motor model, and a simple technique was used to eliminate the chattering phenomenon within sliding-mode control. Comparing with PID control under adjacent cross-coupling control structure, simulation results illustrate the effectiveness and robustness.
