摘要:
针对多叶准直器系统中直线电机受到往复直线运动和旋转运动带来的多周期干扰问题,提出一种多周期迭代滑模控制(M LV SC)算法用于提高直线电机的控制精度。该算法将迭代学习和滑模控制结合起来,利用多个迭代学习项来逼近并抑制多周期干扰,同时采用滑模控制来抑制未知干扰以保证系统的稳定性。通过构造合适的Lyapunov函数,可以证明MLVSC算法的渐近稳定性。在此基础上,基于MLVSC算法设计了直线电机系统的控制器。实验结果表明,MLVSC算法能够对直线电机受到的多周期干扰进行抑制,抑制后的控制误差迅速减小,控制精度提高了81%。
Abstract:
?To tackle the multi-periodic disturbance of linear motor used in multi-leaf collimator system, a control algoritlim of multi-jDeriodic learning variable structure control ( MLVSC) was proposed. The multi-periodic disturbance is caused by recijDrocating motion and rotar motion, and iterative learning and varia-ble structure control were combined to repress it in this algoritlim, where multif)le iterative learning items were used to approximate and compensate multi-periodic disturbance, while variable structure cutilized to suppress unknown disturbance so as to assure the system stability. By constructing the appro-priate Lyapunov function, the asymptotic stability of MLVSC algoritiim was proven. On this basis, the controller for linear motor system based on MLVSC was designed. Experimental results show that t!ie con-trol error of linear motor is rapidly diminis!ied after using MLVSC algorit!im, and the control precision is evidently improved by 81%, indicating the validity of this multi-periodic disturbance rejection method.
