摘要:
针对动圈式永磁平面电机的无位置传感器控制问题,提出一种结合电路能量守恒定律,利用卡尔曼滤波算法进行状态估计得到的动子位置信息来进行实时电流分配,产生作用于动子的悬浮力和水平推力的无位置传感器控制策略。该策略通过实时获取动子线圈端电压和端电流计算得出总功率,减去动子线圈消耗热功率得到推力作用于动子的机械功率,此机械功率在恒定推力控制下反应动子采样时间间隔内位移的大小,以此建立动子位置、速度、加速度的卡尔曼滤波估计算法模型。在此基础上,对控制算法以及控制策略所产生的推力进行仿真,仿真结果验证了控制策略的正确性。
Abstract:
 To solve sensorless control problem of moving-coil permanent magnet planar motor, the following sensorless control strategy was put forward: based on circuit energy conservation,Kalman filtering estimation algorithm was utilized to conduct state estimation for achieving mover position information to distribute real-time current,which produces levitation force and horizontal thrust acting on active cells to control sensorless. The strategy can constantly obtain terminal voltage and current from moving coils to export
total power and get the mechanical power acting on the mover through subtracting the thermal power consumed by the moving coils. The mechanical power reacts the size of the displacement in the mover sampling interval under constant thrust control, so as to establish Kalman filtering estimation algorithm model of the position,velocity and acceleration of the mover. On this basis, taking a simulation for the thrust coming from the control algorithm and the control strategy,and the simulation result was verified
that the control strategy is correct.
