目前直线旋转开关磁阻电机(Linear-rotary switched reluctance motor,LRSRM)只可实现轴向定位控制,两自由度运动方式较为单一.为提高LRSRM轴向控制性能,本文提出了一种轴向速度控制方法,通过线性位置/速度观测器协调控制转子的轴向位移和轴向速度,由转矩与轴向力的数学模型解算出转矩及轴向力绕组的给定电流,再将其分配到对应的绕组导通区间,分别进行电流滞环控制.该方法可以有效调节转子在旋转过程中的轴向定位速度.仿真和实验验证了所提方法的控制效果.
Fast Axial Positioning with Linear-Velocity Control for Linear-Rotary Switched Reluctance Motor
Currently,the axial motion of linear-rotary switched reluctance motor(LRSRM)can only achieve axial positioning,and the two-degree-of-freedom motion is simple.A linear-velocity control method is proposed in the paper to improve the axial control performance.The axial displacement and velocity of rotor are controlled by linear position/velocity observer.The torque winding current and axial-force winding current are calculated by the mathematical model of torque and axial force,and then distributed to the corresponding conducted region for current hysteresis.It can effectively regulate the axial velocity and displacement of the rotor during the rotation process.The effectiveness and accuracy of the proposed method are verified by simulation and experiments.
